Summit Entertainment is developing a feature film adaptation of Top Cow’s comicbook “Alibi”. The comic book centers on a well known socialite whose public presence establishes a perfect alibi for the covert activity of his secret twin brother, a government assassin. Summit has attached John Hlavin to pen the script. He was recently hired to write the fourth installment of “Underworld” for Screen Gems and is developing his Western screenplay “Gunslinger” at Warner Bros.
