I am trying to find out a name to this movie I saw when I was young. I remember towards the end of the movie there was a possible mom and dad on the subway with their little girl she must have been like 7 or 8 and she's dancing I think she was a ballerina and then she just felt weak and she died or passed out and they were carrying her out from the train... Im not sure if she had an illness or something but I just can't figure it out.. please help if you can!:)

I found it... its called Six Weeks" with Dudley Moore.. thank you though anyway for your help!
