Justin wears a t-shirt during the scene when Phil is fixing Justin's car. On the t-shirt is a comic book character's head named Ambush, created by co-writer/director Heath McKnight in 1994 while he was in high school. An "ash can" edition was published that summer (a small prequel comic book) but a regular series never materialized. To keep things "alive," McKnight will occasionally put the hero's llustrated head, the comic, a poster, etc., as an "Easter Egg" in many of his films. In 9:04 AM, it's on Justin's t-shirt and is also on the wall of his apartment's room. In Skye Falling (2001), the character Kianna is reading the comic. McKnight is now working on creating a comic book mini-series and is planning on adapting it into a film with is co-writer Jeremiah Hall (Push/Pull). He hopes to have the comic out in 2011 and the film out by 2013.
