Bonnie and Clyde, with Faye and Warren To Wong Foo, Thanks For Everything, Julie Newmar Patton Evita, the stage play though, not the movie (but I am including this anyway) Abbott and Costello Meet the Killer, Boris Karloff
I've never heard of this movie but the first thing I thought of by the title Mary Poppins. I looked it up and saw a one-sentence summation of the movie's plot -- looks pretty interesting to me.
(All movies, to me, could benefit by summarizing their plots in one sentence, instead of three minute trailers that seem to so often give away huge plot spoilers.)
