Registration Statement on Form S-4
(File No. 333-171819)

Ladies and Gentlemen:

        In connection with the Registration Statement on Form S-4 (File No. 333-171819) (as amended, the "Registration Statement") of AMC Entertainment Inc., a Delaware corporation (the "Company"), the persons listed on Schedule I hereto as Delaware Guarantors (together, the "Delaware Guarantors") and the other subsidiaries of the Company named therein as guarantors (the "Other Guarantors and, together with the Delaware Guarantors, the "Guarantors"), filed with the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended (the "Act"), and the rules and regulations thereunder (the "Rules"), you have asked us to furnish our opinion as to the legality of the securities being registered under the Registration Statement. The Registration Statement relates to the registration under the Act of the Company's $600,000,000 aggregate principal amount of 9.75% Senior Subordinated Notes due 2020 (the "Exchange Notes") and the guarantees of the Exchange Notes by the Guarantors (the "Guarantees").

        The Exchange Notes and the Guarantees are to be offered in exchange for the Company's outstanding $600,000,000 aggregate principal amount of 9.75% Senior Subordinated Notes due 2020 (the "Initial Notes") and the guarantees of the Initial Notes by the Guarantors. The Exchange Notes and the Guarantees will be issued by the Company and the Guarantors, respectively, in accordance with the terms of the Indenture, dated as of December 15, 2010 (the "Indenture"), among the Company, the Guarantors and U.S. Bank National Association, as trustee.

        In connection with the furnishing of this opinion, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents (collectively, the "Documents"):

        1.     the Registration Statement;

        2.     the Indenture, including as exhibits thereto the forms of Exchange Note and Guarantees, included as Exhibit 4.6 to the Registration Statement; and

        3.     the Registration Rights Agreement, dated as of December 15, 2010 (the "Registration Rights Agreement"), among the Company, the Guarantors and Goldman, Sachs & Co., J.P. Morgan Securities LLC, Barclays Capital Inc., Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc. and Foros Securities LLC, as representatives of the initial purchasers of the Initial Notes, included as Exhibit 4.7 to the Registration Statement.

        In addition, we have examined (i) such corporate records of the Company, and each Delaware Guarantor that we have considered appropriate, including a copy of the certificate of incorporation, as amended, and by-laws, as amended, of the Company and each Delaware Guarantor, certified by the Company and each such Delaware Guarantor, respectively, as in effect on the date of this letter, and copies of resolutions of the board of directors of the Company and each such Delaware Guarantor relating to the issuance of the Exchange Notes and the Guarantees, certified by the Company and each such Delaware Guarantor, respectively and (ii) such other certificates, agreements and documents as we deemed relevant and necessary as a basis for the opinions expressed below. We have also relied upon the factual matters contained in the representations and warranties of the Company and the

Guarantors made in the Documents and upon certificates of public officials and the officers of the Company and the Guarantors.

        In our examination of the documents referred to above, we have assumed, without independent investigation, the genuineness of all signatures, the legal capacity of all individuals who have executed any of the documents reviewed by us, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as certified, photostatic, reproduced or conformed copies of valid existing agreements or other documents, the authenticity of all the latter documents and that the statements regarding matters of fact in the certificates, records, agreements, instruments and documents that we have examined are accurate and complete. We have also assumed, without independent investigation, (i) that the Exchange Notes and the Guarantees will be issued as described in the Registration Statement and (ii) that the Exchange Notes and the Guarantees will be in substantially the form attached to the Indenture and that any information omitted from such form will be properly added. We have relied, with the Company's permission, upon the opinion of O'Melveny & Myers LLP, dated as of the date hereof and filed as Exhibit 5.4 to the Registration Statement, as to the due authorization, execution and delivery of the Indenture and the Guarantees by the Other Guarantors incorporated in the state of California and the District of Columbia. We have relied, with the Company's permission, upon the opinion of Quarles & Brady LLP, dated as of the date hereof and filed as Exhibit 5.2 to the Registration Statement, as to the due authorization, execution and delivery of the Indenture and the Guarantees by the Other Guarantors incorporated in the state of Arizona. We have relied, with the Company's permission, upon the opinion of Lathrop & Gage LLP, dated as of the date hereof and filed as Exhibit 5.3 to the Registration Statement, as to the due authorization, execution and delivery of the Indenture and the Guarantees by the Other Guarantors incorporated in the states of Missouri and Kansas.

        Based upon the above, and subject to the stated assumptions, exceptions and qualifications, we are of the opinion that:

        1.     The Exchange Notes and Guarantees have been duly authorized by the Company and each of the Delaware Guarantors.

        2.     The Indenture has been duly authorized, executed and delivered by the Company and each of the Delaware Guarantors.

        3.     When duly issued, authenticated and delivered against the surrender and cancellation of the Initial Notes as set forth in the Registration Statement and in accordance with the terms of the Indenture and the Registration Rights Agreement, the Exchange Notes will be valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms, except that the enforceability of the Exchange Notes may be subject to bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer, moratorium or similar laws affecting creditors' rights generally and subject to general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at law).

        4.     When the Exchange Notes are duly issued, authenticated and delivered against the surrender and cancellation of the Initial Notes as set forth in the Registration Statement and in accordance with the terms of the Indenture and the Registration Rights Agreement, the Guarantees will be valid and legally binding obligations of each of the Guarantors enforceable against each of the Guarantors in accordance with their terms, except that enforceability of the Guarantees may be subject to bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer, moratorium or similar laws affecting creditors' rights generally and subject to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law).

        The opinions expressed above are limited to the laws of the State of New York and the General Corporation Law of the State of Delaware. Our opinion is rendered only with respect to the laws, and the rules, regulations and orders under those laws, that are currently in effect.

        We hereby consent to use of this opinion as an exhibit to the Registration Statement and to the use of our name under the heading "Legal Matters" contained in the prospectus included in the

Registration Statement. In giving this consent, we do not thereby admit that we come within the category of persons whose consent is required by the Act or the Rules.

Very truly yours,

/s/ PAUL, WEISS, RIFKIND, WHARTON & GARRISON LLP
