Neil Patrick Harris Neil Patrick Harris

Neil Patrick Harris fans hoping to see their fave be a cut-up as host of Sunday's Tony Awards (airing at 8 pm/ET, on CBS) will probably get some satisfaction. But those wanting to see the How I Met Your Mother star cut a rug or break out into song might come up empty.

"They have an opening planned that is bigger than they have ever had in Tony history. But I don't think I'm going to be involved in it," Harris shared in a press conference call.

Instead, Harris says he will take a cue from Hugh Jackman's first turn as Tonys host, "where he wasn't on a ton and didn't do a lot of performing, but just tried to make the audience feel welcome and keep things running at a smooth clip."

Is NPH rooting for anyone at this year's salute to the stage? Although Billy Elliot is considered the juggernaut to beat, Harris is holding out hope that Next to Normal — which he just saw and says boasts a "small cast and an amazing score" that he can't stop humming — will collect kudos.

"It would be fun if there were a couple less predictable winners," says Harris.

Asked for updates on two possible sequels he could be involved in, Harris told TVGuide.com that while he's "hoping to get naughty" in A Very Harold & Kumar Christmas (now slated for a November 2010 release), circumstances aren't allowing for a trip back to the lab as viral-video villain Dr. Horrible. Yet.

"We're all gung-ho on a future for it, but [Joss Whedon's] Dollhouse just got picked up and Nathan [Fillion]'s Castle got picked up, and I'm still How I Met Your Mothering," says Harris. "But I think that once all of our other dust settles, we have something to fall back on."
