But Takei has claimed that there's no real feud between them. "It's not tension, it's all coming from Bill," he told The New York Times Magazine in 2015. "Whenever he needs a little publicity for a project, he pumps up the so-called controversy between us." "It's difficult working with someone who is not a team player. The rest of the cast all understand what makes a scene work – it's everybody contributing to it. But Bill is a wonderful actor, and he knows it, and he likes to have the camera on him all the time," Takei added.
