A staple of the comedy genre has forever been watching people get hurt, and nowhere is this more evident than in the continuing legacy of the “Jackass” franchise.What started as a MTV reality series in which various jackasses performed increasingly stupid stunts for the benefit of the cameras before them eventually evolved into a four-film movie franchise spanning two entire decades.“Jackass: The Movie” was released in theaters in 2002 and was intended to be the conclusion to “Jackass” – a feature film capper after a three-season run on TV. But after grossing nearly $80 million on a budget of just $5 million, “Jackass” the movie franchise was born.Johnny Knoxville, Bam Margera, Steve-O, Chris Pontius and many, many more continued to make fools of themselves for the camera in three additional feature films released across the next 20 years.“Jackass: Number Two” arrived in 2006, while “Jackass: 3D” took advantage of Hollywood’s 3D craze in 2010.
