This Amendment No. 3 to Schedule 13D (this “Amendment”) is being filed jointly by Dong Yu (the “Founder”), Vantage Global Holdings Ltd (“Vantage”) and Skillgreat Limited (“Skillgreat”, and together with the Founder and Vantage, the “Reporting Persons”) relating to the ordinary shares, par value $0.0005 per share (the “Ordinary Shares”), each Ordinary Share represented by two American depositary shares (the “ADSs”), of Bona Film Group Limited (the “Issuer”), an exempted company organized under the laws of the Cayman Islands. This Amendment amends and supplements the Statement on Schedule 13D originally filed with the Securities and Exchange Commission (the “SEC”) on May 25, 2012 (as amended by Amendment No. 1 filed with the SEC on October 9, 2013 and Amendment No. 2 filed with the SEC on July 25, 2014, the “Original Statement”) by the Reporting Persons. Only those items in the Original Statement amended by this Amendment are reported herein. Capitalized terms not otherwise defined herein shall have their respective meanings given to them in the Original Statement.

Item 3. Source and Amount of Funds or Other Consideration

Item 3 is hereby amended by adding at the end thereof the following paragraphs:

“The information set forth in Items 4 and 6 of this Schedule 13D is incorporated by reference in this Item 3.

The Reporting Persons, together with Fosun International Limited, Orrick Investments Limited, Peak Reinsurance Company Limited and Fidelidade-Companhia de Seguros, S.A. (collectively, “Fosun Entities”) and Sequoia Capital China I, L.P., Sequoia Capital China Partners Fund I, L.P. and Sequoia Capital China Principals Fund I, L.P. (collectively “Sequoia Entities”, and together with Fosun Entities, each a “Sponsor”, and collectively, the “Sponsors”, and together with the Reporting Persons, the “Consortium”) anticipate that, at the price per Ordinary Share set forth in the Proposal (as described in Item 4 below), approximately US$409.3 million will be expended in acquiring approximately 14.9 million outstanding Ordinary Shares (calculated based on the number of Ordinary Shares outstanding as of June 12, 2015) and/or any share-based awards of the Company, in each case other than held by the Consortium (as defined below), in connection with the Transaction (as defined below).

It is anticipated that funding for the Transaction will be provided by a combination of debt and/or equity capital. Equity financing will be provided by the Consortium, and any additional members accepted into the Consortium, in the form of cash and rollover equity in the Company. Debt financing is expected to be provided by loans from third party financial institutions.”

Item 4. Purpose of Transaction

Item 4 is hereby amended by adding at the end thereof the following paragraphs:

“The information set forth in Items 3 and 6 of this Schedule 13D is incorporated by reference in this Item 4.

On June 12, 2015, the Reporting Persons (other than Vantage Global Holdings Ltd) entered into a consortium agreement with the Sponsors (the “Consortium Agreement”), pursuant to which the Consortium will cooperate in good faith in connection with an acquisition transaction (the “Transaction”) with respect to the Issuer as contemplated by the Proposal (as defined below). The Consortium Agreement provides, among other things, for: cooperation in arranging financing; engaging advisors; cooperation in obtaining applicable governmental, statutory, regulatory or other approvals, licenses, waivers or exemptions for the consummation of the Transaction; and cooperation in preparing definitive documentation with respect to the Transaction. During the period beginning on the date of the Consortium Agreement and ending on the earlier of (a) the 9-month anniversary of the date of the Consortium Agreement and (b) the termination of the Consortium Agreement on the occurrence of other termination events, members of the Consortium have agreed to work exclusively with each other with respect to the Transaction.

On June 12, 2015, the Consortium submitted a non-binding proposal (the “Proposal”) to the Company’s board of directors for the Transaction. Under the Proposal, members of the Consortium propose to acquire, through an acquisition vehicle to be formed by them, all of the Ordinary Shares owned by shareholders of the Company other than the Consortium for US$13.70 per ADS or US$27.40 per Ordinary Share in cash, representing a premium of 23.6% to the volume-weighted average closing price during the last 30 trading days. The Consortium intends to finance the Transaction through a combination of equity and/or debt financing. For a brief description of the financing plan, please refer to Item 3.

The Proposal also provides that, among other things, the Consortium will (a) conduct customary legal, financial and accounting due diligence on the Company and (b) negotiate and execute definitive agreements with respect to the Transaction that will provide for representations, warranties, covenants and conditions which are typical, customary and appropriate for transactions of this type. In the Proposal, members of the Consortium also stated that they expect that the independent members of the Company’s board of directors will proceed to consider the Proposal and the Transaction and that the Founder will recuse himself from participating in any deliberations and decisions related to the Transaction by the Company’s board of directors.

If the transactions contemplated under the Proposal are completed, the Ordinary Shares and ADSs would become eligible for termination of registration pursuant to Section 12(b) of the Securities Act of 1933 and the ADSs representing Ordinary Shares would be delisted from the NASDAQ Global Select Market.

References to the Consortium Agreement and the Proposal in this Schedule 13D are qualified in their entirety by reference to the Consortium Agreement and the Proposal, copies of which are attached hereto as Exhibits 99.2 and 99.3 and incorporated herein by reference in their entirety.”

Item 5. Interest in Securities of the Issuer

The first and second paragraphs of Item 5 is hereby amended and restated as follows:

“(a) and (b) The information set forth in the cover pages of this Schedule 13D is incorporated herein by reference. Skillgreat will be the record owner of 8,530,992 Ordinary Shares, which includes 194,345 Ordinary Shares held by Skillgreat Limited for other persons. The Reporting Persons expressly disclaim beneficial ownership of the 194,345 Ordinary Shares held by Skillgreat on behalf of others. Vantage is the record owner of 26,991 Orinary Shares.

The Reporting Persons may be deemed to be members of a “group” with the Sponsors pursuant to Section 13(d) of the Act as a result of entering into the Consortium Agreement and the submission of the Proposal (each as defined in Item 4). However, each Reporting Person expressly disclaims beneficial ownership of the Ordinary Shares beneficially owned by the Sponsors. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that any of the Reporting Persons beneficially owns any Ordinary Shares of the Issuer that are beneficially owned by any of the Sponsors. The Reporting Persons are only responsible for the information contained in this Schedule 13D and assume no responsibility for information contained in any other Schedules 13D filed by any of the Sponsors.”

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

Item 6 is hereby amended to add at the end thereof the following paragraphs:

“The information set forth in Items 3, 4, 5 and 7 of this Schedule 13D is incorporated by reference in this Item 6.

To the best knowledge of the Reporting Persons, except as provided herein, there are no other contracts, arrangements, understandings or relationships (legal or otherwise) among the Reporting Persons and between any of the Reporting Persons and any other person with respect to any securities of the Issuer, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies, or a pledge or contingency, the occurrence of which would give another person voting power over the securities of the Company.”
