LONDON - Hollywood actress Megan Fox says that it was a nightmare to work with “Transformers” director Michael Bay because he wants to create an infamous mad-man kind of reputation for himself.

Throwing light on her experience of working with the director, Fox revealed that Bay was a hard taskmaster and that she thinks he’s slightly mad, reported contactmusic.com.

“I really wish I could go loose on this one - he’s (Bay) like Napoleon and he wants to create this insane, infamous mad-man reputation. He wants to be like Hitler on his sets, and he is. So he’s a nightmare to work for,” said the actress.
