According to Showbizspy, Director Kevin Smith supports Joe Johnston's (Captain America) idea for a full length Boba Fett film.
“There’s no good reason not to let Joe Johnston make a Boba Fett movie,” says Kevin.
“Give it to him! Why the #$%@ not? There’s easy money to be made and, plus, you’ll make your audience happy. For years we are all like, ‘We love Boba Fett! We don’t know why, but we like him. He doesn’t do much, but we like him.’ Why George Lucas wouldn’t green light that? That’s just printing money.”
