Name the Movie

Abandoned

See if you can name the movie the following quote is taken from.
"You're not my real dad are you?"
Leave one for us to guess too.

Nobody wants to play? OK, I can take a hint.

Familiar, but I can't think of what it came from.

I can't figure it out.
How about this one, "No man likes a slut for long".

inbyathread got it right.

momz:
It was To Sir, With Love starring Sidney Poitier, which I watched over the weekend. I prefer describing behavior to name calling. Anyway, I disagree with the esteemed Sir on this one.

How about this one:
"The man at the imperial staff meeting may not have been the real Sir Walter, but the man who came here most certainly was."
Hint, the movie also has these lines:
"Ariadne gave the thread to her lover, so he can escape from the labyrinth after slaying the monster."
"Aye, that's the Tories for ye."
And one of the actors in the movie also starred in Titanic.
Okay, that should be enough to easily identify the film.
