No he’s not. They’ve already shown they can do story without him. And he is after all a movie guy, not a TV guy. TV is a grind, it’s hard to find time for other projects. And as a movie guy he’s not built for doing the same character over and over for years. The new show will do fine. It might, or might not, bring other actors from the show in. But all shows end, everybody in the business knows that. A 5 year gig is a great run, most TV gigs never go to series, they’re 3 weeks to shoot a pilot that might not even get aired. Actors spend more time looking for work than doing the work. Everybody is used to it.
With Bruce Willis and Clint Eastwood calling it quits, why tie yourself to a television series character?
