Producer Alleges Attack From Brendan Fraser

The man who filed the suit is Todd Moyer -- one of the producers on the movie "The Legend of William Tell" ... a movie that has been in the works since 2011.

In his suit, Moyer claims he was hanging out at the Hilton Hotel in Indianapolis on July 27, 2011 ... when an "intoxicated" Brendan Fraser began to "physically push, verbally threaten and poke [Moyer] in the chest repeatedly." Moyer doesn't specify what led to the alleged attack.

But six months later ... on January 31, 2012 ... Moyer says Fraser struck again -- this time during a meeting about the movie at the offices of Brillstein Entertainment Partners.

According to Moyer, Fraser demanded that Moyer hire a producer named Charlotte Huggins to work on "Tell" ... but Moyer refused. That's when Fraser allegedly went nuts -- screaming threats and striking Moyer in the chest at least 20 times.
