William Shatner is aiming his phaser at his former 'Star Trek' colleague George Takei, calling him 'sick' and 'psychotic' in a YouTube rant.

Ticked off that Takei didn't invite him to his recent California wedding, Shatner trashed the actor who played Mr. Sulu on the 1960s sci-fi series as if he were a villainous Klingon.
