US cable channel Comedy Central is gearing up for the launch of Graham Norton's new chat show on June 24.

The Graham Norton Effect will be of a similar format to his Channel 4 shows: "Take an irreverent talk show host, add truckloads of celebrities, an unsuspecting studio audience and an Internet connection -- and you've got The Graham Norton Effect," the promos explain.

The show will air on Thursday nights at 10pm ET. Effect is taped at 7:30pm on Tuesdays in New York City, with tickets available from Broadway Video.
