Trivia: In the prison sequence, at one point a TV is visible in the background playing the famous and infamous cult-film "The Toxic Avenger." "The Toxic Avenger" was produced by the independent studio Troma Entertainment. Director James Gunn actually got his start working for Troma, writing the cult favorite "Tromeo and Juliet," and doing various other behind-the-scenes jobs on several other Troma productions. As a thank-you, Gunn often includes Troma easter-eggs in his films.
Trivia: A lot of people involved in James Gunn's "Guardian of the Galaxy Vol. 2" also appeared in, or worked on, Gunn's "The Suicide Squad." For example; Michael Rooker, Sylvester Stallone, Sean Gunn, Steve Agee, Stephen Blackehart, Pom Klementieff, and Terence Rosemore appeared in both films. And one of the rats that played Sebastian is named Crisp Ratt. Henry Braham and Fred Raskin did the cinematography and film editing for both films. Just to name a few.
