It appears that the rumors of 'Iron Man 4' ever making its way to the screen might need to be laid to rest at least for a while since Robert Downey, Jr. May not go through with it.
While there is no official word if there will be an 'Iron Man 4,' it looks like there is a possibility that the series could continue based off the latest Marvel short film 'All Hail the King.'
Ben Kingsley was recently in a short Marvel film called 'All Hail the King' where he reprises his role Trevor Slattery, which could potentially hint at the possibility of taking that reprisal to an 'Iron Man 4.'
