9 crucial movie scenes that really shouldn't have been deleted

Some movies are littered with confusing moments or plot threads that just don't quite make sense.

We're left with the feeling that we've missed something.... And often it turns out that we have. We've missed a vital scene which explained everything and for some strange reason ended up on the cutting room floor.

How about the scene where Indiana Jones learns that he can't look at the Arc? Or the bit in Independence Day when Jeff Goldbum's character actually manages to upload a virus to the alien mothership? It's all here – and it all makes so much more sense.
