After not hearing back from actor Charlie Sheen, "Entourage" creator Doug Ellin talked about what it means for Sheen’s possible appearance on the HBO show, reports EW.com’s Inside TV blog.

“I never heard back. Looks like it will not be happening,” Ellin said. “I could have come up with some good stuff. I didn’t really plan anything, but I would have.”

The HBO series is halfway through taping its eighth and last season, which will include guest appearances by Johnny Galecki of "The Big Bang Theory" and Andrew Dice Clay, the story says.
