That would be the film Meet the Spartans which is the spoof of 2007 film 300. And it also directs parodies at various films.

The worst part about this movie is the lead actor Sean Maguire who play the King Leonidas. Too much facial expressions and too hard trying to be funny sink the whole movie.

The director who also directed other parody movies such as Scary Movie and Date Movie throw in every film jokes whether related to the film or not. For example they bring in Rocky who have Stalone accent to help Parsians fight the Spartans. WTF!!

And the jokes goes all way down to common denominator of being nasty and repulsive. If you can stomach the first five minutes of movie in the ball-licking scene where the king is sitting on stool with a dog underneat, you're better man than I am
