This week, Kevin Connolly is taking a stab at directing an episode of 'Entourage,' and sources on set tell PopEater that he allegedly kept the cast up late, making them re-shoot several scenes -- even though everyone thought the first few takes were great.

The crew admits shoots have never run that long, but sources claim Connolly "is an extreme perfectionist." Of course, the actors started to get restless when he kept making them redo scenes.

"Everyone was getting annoyed because there was no reason it should have taken that long to shoot," sources reveal.
