Joss Whedon, as we know, is an all-star, but the downside to that is he can't take on everything.
With new "Star Wars" movies on the horizon, Whedon was eager to see if he could be a candidate to direct - before remembering that he's already working on "S.H.I.E.L.D." for ABC and a sequel to 2012's blockbuster "Avengers."
"I'm as angry as you should be," Whedon said about being unable to take on a "Star Wars"-sized project. "When I heard that I was like, 'I wonder... no, I really can't do that. Oh, I already have a job.' I wouldn't clear the Avengers. I'm having so much fun with that sequel right now, just with the script, that I couldn't imagine not doing it."
In essence he's doing double-duty with that storyline, because his show - which ABC thinks has potential to get a series order - features the same covert intelligence agency that was featured in "Avengers."
Whedon, also beloved for his small screen work with shows like "Firefly" and "Buffy the Vampire Slayer," said "S.H.I.E.L.D." is reminding him how taxing television can be.
"I'd forgotten how much work TV was so I'm cranky at everybody all the time," he said. "But it's really fun. We have a beautiful ensemble and we're having so much fun coming up with the stories. It really is like working at Marvel Comics, which was a dream of mine as a kid because this little book 'S.H.I.E.L.D.' that not that many people read ... It's not as big as the movies [and] we're telling smaller stories but we get to do it more often. "
But just because he doesn't have time to direct "Star Wars" doesn't mean he doesn't have opinions on how it should play out.
"Oh I've got a lot of things. Where's my list I'm carrying on me?" Whedon joked. "But you know, I'd like to see a little edge. We all missed the Han [Solo] of it. It got very portentous, which was justified by the story, but I think we'd all like to see a little anarchy in the mix."
