Even for a comic book movie screenwriting veteran such as Zak Penn, the task of bringing multiple Marvel characters together in one film is a daunting one. It’s so daunting, in fact, that Penn isn’t even sure it’ll work when he has to write “The Avengers” this summer.

“It’s hard to make a good movie,” the screenwriter told a crowd gathered at a Los Angeles Film Festival panel last night, according to Sci Fi Wire. “We all have the best intentions, and it still might suck.”

That won’t stop Penn from trying. Having already written mutant mash-ups in “X2: X-Men United” and “X-Men: The Last Stand,” Penn is no stranger to juggling a multitude of superheroes. Believe it or not, he actually wanted to include more comic book characters in those films, as Penn said that he’d planned to incorporate the Fantastic Four into the X-Men movies. Unfortunately, Fox wasn’t warm to the idea, signifying a very different approach from Marvel Studios’ current edict.

“[Marvel wants] to see that they’re all connected, not like the Fantastic Four can’t come into the X-Men world, like I was told [by Fox],” Penn revealed, saying that he’d be involved in the development of “Thor” and “The First Avenger: Captain America,” both of which will debut before “The Avengers.”

“I’m taking a meeting next week with the ‘Thor’ and ‘Captain America’ people, and we are all going to get together, and I will see what is going to happen,” he said. “I’ll see where they are leaving the characters; it’s pretty complicated.”

Even if “The Avengers” doesn’t work out quite as well as he’d hope, Penn suggested that the film is – at the very least – in the right hands. He praised Marvel’s work as a studio thus far, pointing to their first-hand knowledge of the source material as the reason for their success.

“Marvel is autonomous now,” Penn said. “It is night and day: Everyone has read every comic. They know how to make a cool movie.
