Benedict Cumberbatch caught on video in heated cycling confrontation over running a red light in London

Benedict Cumberbatch got into a heated exchange with a fellow cyclist in London.

The "Doctor Strange" star was caught on video getting off of his bike and confronting an unknown man who accused him of running a red light.

"You’re deluded, you’re lying. I was behind you the entire time," the unknown cyclist said in the video.

Cumberbatch told the man he was "verbally" abusing him. "Oh no, I verbally abused the guy who completely repeatedly broke the law," the man said. "I did it once," Cumberbatch replied.

An eyewitness said the interaction was "pompous road rage" and it almost "felt staged," according to SWNS.

"Benedict still managed to charm everyone watching even though he was having a meltdown. They went at each other about five times," the eyewitness added.

The eyewitness said that Cumberbatch and the other cyclist "blocked the lane so no one else could get through." The man who saw the incident said that the unknown biker followed Cumberbatch until he would pull his bike over.

"The masked guy was obviously some kind of vigilante — he was really taken aback when he saw it was Benedict Cumberbatch, but he doubled down on his rage," the witness said.

The man added, "I don’t condone dangerous driving, but for this guy to follow him and cause an incident like this was worse than Benedict slowly cutting that light."
