Wednesdays Movie Mashup No. 25

Even after saying he was giving up, Nick needed only a small hint to get last week's clue.  It was tougher, with one being an older film, and the other not a whole new word.  Well done.
Last week's clue: A younger woman tries to steal the place of her mentor while a woman examines her romantic past and the current romantic lives of her daughters.Answer: All About Evening
