However, we get some bad news from director James Gunn.
He says Nathan Fillion is not playing Nova.
The good news?
Gunn didn’t come out and specifically state there is no Richard Rider Nova in the movie; so we can at least hope Richard Rider is still set to appear (even though we’ve been told no Nova).
