     Re: Registration Statement on Form S-3

Ladies and Gentlemen:

     We have acted as counsel to Entertainment Properties Trust, a Maryland real
estate  investment trust (the "Issuer"),  in connection with the public offering
under  the  Securities  Act of 1933,  as  amended  (the  "Securities  Act"),  of
1,150,000 common shares of beneficial interest of the Company (including 150,000
shares  to  cover   over-allotments,   if  any,  the  "Shares")  pursuant  to  a
registration  statement  on Form S-3  filed  with the  Securities  and  Exchange
Commission  (the  "Commission")  on March 15, 2004,  File No.  333-113626  (such
registration statement, as amended or supplemented is hereinafter referred to as
the  "Registration  Statement").  This opinion is being  delivered in accordance
with the  requirement  of Item  601(b)(5) of Regulation S-K under the Securities
Act.  Capitalized  terms used but not otherwise defined herein have the meanings
ascribed to them in the Registration Statement.

     In  connection  with this  opinion,  we have  examined  originals or copies
certified  or  otherwise  identified  to our  satisfaction  of  such  documents,
corporate  records and other  instruments  as we have deemed  necessary  for the
purposes of this opinion,  including (i) the Amended and Restated Declaration of
Trust and Bylaws of the  Issuer,  (ii)  minutes  and  records  of the  corporate
proceedings of the Issuer with respect to the issuance of the Shares,  (iii) the
Registration  Statement,  and  (iv)  the  Underwriting  Agreement,  dated  as of
February 3, 2006,  between the Issuer and RBC Capital Markets  Corporation  (the
"Underwriting Agreement").

     For  purposes of this  opinion,  we have  assumed the  authenticity  of all
documents  submitted to us as originals,  the conformity to the originals of all
documents submitted to us as copies and the authenticity of the originals of all
documents submitted to us as copies. We have also assumed the genuineness of the
signatures  of persons  signing  all  documents  in  connection  with which this
opinion is rendered,  the  authority  of such  persons  signing on behalf of the
parties thereto other than the Issuer and the due  authorization,  execution and
delivery of all documents by the parties  thereto  other than the Issuer.  As to
any  facts  material  to  the  opinion   expressed  herein  which  we  have  not
independently  established  or verified,  we have relied upon the statements and
representations of officers and other representatives of the Issuer and others.

     Our  opinion  expressed  below is  subject  to the  qualifications  that we
express no opinion as to the applicability of, compliance with, or effect of (i)
applicable bankruptcy, insolvency,

reorganization,  moratorium,  arrangement  and other laws  affecting  creditors'
rights,  including,  without  limitation,  the effect of statutory or other laws
regarding   fraudulent   conveyances,   fraudulent  transfers  and  preferential
transfers,  (ii) the  limitations  imposed  by  general  principles  of  equity,
including,  without limitation,  concepts of materiality,  reasonableness,  good
faith and fair dealing and the possible  unavailability of specific  performance
or injunctive relief regardless of whether  considered in a proceeding in equity
or at law; and (iii) public policy  considerations which may limit the rights of
parties to obtain certain remedies.

     We  render  no  opinion  herein  as to  matters  involving  the laws of any
jurisdiction  other than the present laws of the United  States of America,  the
present laws of the State of Missouri  (excluding  local laws), the present laws
of the State of New York (excluding local laws),  the Maryland  Corporations and
Associations Act, and the present judicial  interpretations  thereof.  We advise
you that the issues  addressed  by this  opinion  may be governed in whole or in
part by other  laws,  and we  express no  opinion  as to  whether  any  relevant
difference exists between the laws upon which our opinion is based and any other
laws that may actually govern.

     Based upon and subject to the assumptions,  qualifications,  exclusions and
other  limitations  contained  in this  letter,  we are of the opinion  that the
Shares  have been duly  authorized  and,  when  issued  in  accordance  with the
Registration Statement, will be validly issued, fully paid and non-assessable.

     This opinion is limited to the specific  issues  addressed  herein,  and no
opinion may be inferred or implied  beyond that expressly  stated  herein.  This
opinion  shall  not be  construed  as or  deemed to be a  guaranty  or  insuring
agreement. This opinion is rendered on the date hereof and we have no continuing
obligation  hereunder  to  inform  you of  changes  of law,  including  judicial
interpretations  of law,  or of facts of which we  become  aware  after the date
hereof.

     We consent to the filing of this opinion with the  Commission as an exhibit
to the Registration Statement and to the reference to our firm under the caption
"Legal Opinions" in the Registration  Statement and accompanying  prospectus and
under the caption "Legal Matters" in the prospectus supplement.

                                         Very truly yours,
