The marketing of Deadpool utilized various unconventional social media and promotional strategies that matched the film's unconventional and comedic tone. This included using the dating app Tinder, funny billboards, attending Comic-Con, a "12 Days of Deadpool" viral campaign, casting Ryan Reynolds who was a long-time supporter of the film, three trailers (including an R-rated red band trailer), partnering with cancer charities, and having Deadpool make comedic appearances on TV shows to promote the film. These unique marketing tactics helped generate excitement among fans and brought wider attention to the film.
