Cal: You know, it’s a pity I didn’t keep that drawing. It’ll be worth a lot more by morning.

Rose: You unimaginable b*stard.

This quote comes from the movie ‘Titanic’. The movie came out in 1997 and has since been re-released a few times when new technology would come out (3D, 4K). | Titanic (1997) was produced by Paramount Pictures

Quote meaning:

Cal is talking about the drawing of Rose. Art rises in value after the artist’s death (Jack’s in this case).
