When Cale has just come on board the ship with Akema and Corso, he's in a room with Corso talking about the Titan, etc. It's the scene where he says, "If I don't like the way things are going, I'll show you just how much like my father I am, I'll leave." It's before he says that though.

There's a jug, or pitcher, with whatever they are drinking in it. When Corso goes to pour Cale a drink, it looks like it only has enough left in it for one more glass, so Cale's should have been the last. But when Corso puts it down, it's about half full again. How did that happen? Anyway, it keeps changing throughout the scene and at the end the pitcher is almost full. Anyway, it's not that big, just though I would point it out.
