The Suicide Squad will feature a cameo from its modern creator, John Ostrander.
Writer/director James Gunn replied to Twitter user Justin Mevorah, who asked if Ostrander would appear in the film based on a photo featuring the writer with Michael Rooker's Savant. "Good eye, Justin!" Gunn wrote. "Yes, John Ostrander- the creator of the late '80's Squad in the comics- who just happens to have started in the entertainment industry as an actor (he's really good!) - plays Dr. Fitzgibbon in The Suicide Squad."
Ostrander first introduced the Suicide Squad in the Legends miniseries for DC, which he helped plot. He would later launch the Squad into their own title in 1987 with artist Luke McDonnell and developed the role of Oracle for Barbara Gordon with his late wife Kim Yale. The Suicide Squad features several supervillains coerced into black ops missions for the government, in order to reduce their prison sentiment.
Gunn has featured a character named "Fitzgibbon" in all of his films, named after a family friend. A Dr. Fitzgibbon appeared as Meredith Quill's physician in Guardians of the Galaxy. Though the extent of Ostrander's role has yet to be revealed, producer Peter Safran hinted at Nazi-era experiments and prisons.
