When Langston receives the box from Gloria, the photo inside is from Laurence Fishburne's role in Apocalypse Now.
When Langston is looking over his package that he received from Gloria, you can see a pin in the box that says, "I like Ike". Which is a coincidence because Lawrence Fishburn plays Ike Turner in, "What's love got to do with it". However, the Ike from "I Like Ike" is Dwight D. Eisenhower who had the badges made for his Presidential campain in 1952.
Both Cynthia Watros and Mark Pellegrino acted in the series LOST, although neither had any scenes together.
