There are loads of movies in which men try to pass themselves off as women. How many movies are there in which women try to pose as men? I can think of:
Hillary Swank in “Boys Don’t Cry”
Gwyneth Paltrow in “Shakespeare in Love”
Miranda Otto in “Return of the King”
“Mulan”
Julie Andrews in “Victor Victoria”
Beverly of Graustark (1926)
Same as the book, with Marion Davies playing Beverly who dresses as her cousin Oscar to save The Kingdom of Graustark.
A Florida Enchantment (1914)
A surprising good film (the premise sounds incredibly stupid, but I always take the chance to see silents in real theatres when they play) about a woman (Edith Storey) who, by way of magic beans, turns into a man so that she may flirt with women.
In the end, it all turns out to be a dream.
The House with Closed Shutters (1910)
A D.W. Griffith film about a man who deserts the Confederate army and his sister who, dressed as him, takes his place so that the family is not disgraced.
I Don’t Want to be a Man! (1919)
A funny movie about a girl who thinks the life of women is boring, so she dons formal wear and goes out a-drinkin’ with the boys.
Little Lord Fauntleroy (1921)
29 year old Mary Pickford dressed as a 12 year old (approx., I don’t remember if an exact age is mentioned) boy. Not quite what you’re looking for, since in the film she’s supposed to be male, not just be dressed as a male, but it’s worth a mention.
Just One of the Guys: A high school reporter dresses up as a girl and enrolls at a rival school to prove that the rejection of her newspaper article wes sexist.
There is a Mardi Gras party. The main male character goes in drag; one of the four daughters of the house where he is a guest goes dressed as a guy. The lesbian daughter.
It’s a Spanish movie, got nominated for the Oscars for Best Foreign Language Movie. For some reason IMDB lists it as French… they must think that sounds snazzier. I once watched it with an American boyfriend (we had picked one movie each and rolled dice to see which got played first): he didn’t speak a word of Spanish and of course there are some in-jokes that you can’t understand unless you know quite a bit about Spanish history, but he was laughing so hard I would occasionally stop the tape and turn it back a bit. He ended up sitting on the floor so he wouldn’t roll off the armchair again.
Briefly, A black male airplane passenger is revealed to “really” be Drew Barrymore’s character at the start of Charlie’s Angels. A murderous mob of men almost lynches a crooked ointment salemen, one of whom turns out to be the mannish sister of the eponymous Little Big Man. In Dragonslayer, a young maiden passes herself off as a boy to prevent being ritually sacrificed to a dragon. Natalie Portman very briefly dresses up as Charlie Chaplin in Leon (The Professional). I think. I think Diane Weist dresses as a man to escape the attention of a tabloid photographer at the end of The Birdcage but I might be mistaken.
I wouldn’t include this. The other movies listed are all ‘woman dresses as man as part of some plan.’ Eomer puts on some armor and calls herself Dernhelm because she wants to go and fight. Terry dresses as a boy to sell her article on school lunch, then lives as a boy as fodder another article. Brandon Tina, OTOH, was just a transsexual trying to live the way he felt.
