Could Nathan Fillion have a cameo role in the upcoming “Guardians of the galaxy movie? The “Castle” and “Firefly” star hinted that he might during a recent appearance at the Wizard World Comic Con in St. Louis.

The news popped up unexpectedly during a “Firefly” reunion panel with Fillion, Adam Baldwin and Alan Tudyk in attendance for reminiscing and a Q&A. “Guardians of the Galaxy” came up in a fan question shortly before the panel ended.

When asked if he had maybe wanted to get a role in “Guardians of the Galaxy,” Fillion gave a surprising and hint-heavy reply:

“Wanting to get a part? Or maybe did … I’m just saying maybe. Maybe you’ll be surprised. Maybe check the credits.”

Unfortunately, that’s all the information Fillion gave (check out the video starting at about 38:50 for the discussion), so fans will have to wait until “Guardians of the Galaxy” is released on Aug. 1, 2014.
