What Do They Have In Common?

I found this game on forum that I'm a member of and I thought it would be fun for everyone to play on here. Here's how the game goes...

You are going to name three things (movies, actors, actresses, books, etc) and the next person has to say what they have in common.

Example:
Daniel Radcliffe
Emma Watson
Rupert Grint

What do they have in common?

Answer: They are three main stars of the Harry Potter movie series.

Then you are going to add your three things, and so on and so forth.

I'll start:

Terminator Salvation
Batman Begins
The Dark Knight

They all have Christian Bale in them.

John Robert Hoffman
Johnny Depp
Martin Short
