MSN have more fuel to add to the ‘so which superhero movie is Jessica Simpson reportedly involved with?’ fire. The site doesn’t say which one she’s up for, just that the singer has been cast in an upcoming Marvel Comics-based action adventure film, due for summer 2004 release. As Superhero Hype adds, that means it’s either – “Blade : Trinity” or “Spider-Man 2”, both due for release next Summer. Meantime, Simpson’s also apparently up for the lead roles in new movie versions of “Bye Bye Birdie” and “I Dream of Jeannie”. Maybe this is the time to tip producers off to the fact that Jessica was simply playing herself in the reality series, not acting.But then again, I’m the last person to be whining about pop stars heading into films, having eaten my words once before – with Mandy Moore and her knockout debut.
