Ryan Dunn appeared in all of the Jackass movies and may best be remembered for sticking a Hot Wheels car up his ass. He died early around 2:30 a.m. on Monday in Pennsylvania in a horrific crash that "fully engulfed" his 2007 Porsche 911 GT3 in flames. Dunn was likely speeding, according to the report. An unidentified passenger also died. At 12:15 a.m., a photograph appeared on Dunn's Twitter account showing him and two other men posing with drinks. No word yet if alcohol was a factor in the crash.
