British thespian Patrick Stewart upset fans following a theater performance in Scotland by launching a foul-mouthed tirade at a man who allegedly took a picture of him onstage, according to reports.

The actor is currently taking part in a touring production of Samuel Beckett's Waiting for Godot alongside his X-Men co-star Ian McKellen.

And after a performance in Edinburgh, Scotland earlier this week, the star is said to have accosted an autograph hunter outside the King's Theater, accusing him of using a camera during the performance.

A source tells Scotland's Daily Record newspaper, "There were at least 40 people waiting for autographs and this guy had a big camera and was waiting at the front of the queue. The woman with the guy was getting her program signed. Stewart suddenly looked up and said, 'Are you the asshole who was sitting at the front tonight? You know, what I really want to know is how you can sleep at night? I really hope you're pleased with yourself.'

"The woman looked horrified and clearly upset and walked off but the guy braved it out. Someone said he tried to take a sneaky picture of McKellan and Stewart taking their encore at the end of the show."

A spokeswoman for the theater confirmed the actors had complained about snappers in the audience, adding, "We have received a number of complaints from performers and audience. It is disappointing that these people are willing to risk ruining the evening for everyone else."
