I'm looking for the title to a 90's movie geared towards older children. A girl disguises herself as a boy to be accepted by a group of boys. A scene that sticks out in my mind most is when they were all fishing and a hook got stuck in one of the boys' hand and she tried to act manly about it even though she was squeamish.

Not sure of the movie your looking for.. but here is a list of lots of movies involving cross dressing.. they have a lot of good one in here I've seen.. but can't think of yours at the moment... good luck,,

Scroll down to the film and video section!!

That movie would be "Just one of the guys"

Just One of the Guys (1985) (http://www.imdb.com/title/tt0089393/)

I was thinking that too at first, cause I love that movie.. but I don't recall a part were they go fishing? But good answer, hope we were able too help:)

Yeah... there is no fishing scene in Just One of the Guys... and she is not dressing as a boy to be accepted by the other boys... she believes her article isn't accepted into the summer internship program because she is a girl. This was my first thought as well.

Is it "She's the Man" with Amanda Bynes? Where she is dressing and acting like her brother and playing on his soccer team?

"Boys don't cry" with Hilary Swank?
