US comedian Dane Cook has apologised for making a joke about the deadly Colorado cinema massacre, admitting he made a bad judgement call.
Cook found himself under fire from members of the public after he made light of the Aurora shooting during a stand-up gig at the Laugh Factory in Los Angeles on Thursday.
Twelve people were shot dead when suspect James Holmes allegedly stormed into a midnight screening of The Dark Knight Rises and opened fire. 58 others were injured.
Poking fun at the incident, Cook joked to the Laugh Factory crowd that because the movie was so bad at least one person's reaction to the film probably would have been just "shoot me", if the Holmes incident hadn't occurred.
Video footage of the ill-advised material was posted online soon after the show, prompting disgusted fans to attack Cook via Twitter.
Now the actor has responded to the criticism and has said sorry for his actions.
In a series of Twitter posts on Friday, he wrote, "I am devastated by the recent tragedy in Colorado & did not mean to make light of what happened.
"I made a bad judgment call with my material last night & regret making a joke at such a sensitive time. My heart goes out to all of the families & friends of the victims."
