It seems that NBC is pulling out some big guns for its premiere week with another high-profile guest star on an NBC season premiere. Ausiello Files is reporting that Dolph Lundgren will be guest-starring on the Season 4 premiere of Chuck.

While details on Lundgren's character weren't available, the news was confirmed just minutes ago by showrunner Josh Schwartz with the following tweet.

"Yes it's true. Dolph Lundgren to try and "break" Chuck Bartowski in Season 4 premiere."

The site also reported that Harry Dean Stanton will be guest-starring on the Season 4 premiere as well, although no details on his character were given either.

We reported earlier today that Betty White would be guest starring on another NBC series, Community. We'll be sure to keep you posted on any further Chuck news as soon as we have more information.
