Dillon Casey on Torchwood's Miracle Day.

TV Dillon Casey played Brad, Captain Jack's one night stand, in Dead of Night, episode three of Miracle Day:

"When Dillon Casey landed his first role in the BBC science fiction series Torchwood, he had no idea what he was getting into. Mostly because he hadn’t read the script.

“They kept asking me if I would be OK being intimate with another guy,” said Casey.

That other guy turned out to be star John Barrowman.

But Casey knew what he had to do.

“I had to out-gay John Barrowman,” Casey said of his gay co-star, whose Torchwood character is bisexual. “I was biting his earlobes. . . . I went for it.”
