There have been other "brides being chased by T-Rex" photos before.
This one wins.
According to CBS, actor Jeff Goldblum agreed to pose for a shot taken by photographer Adam Biesenthal for the wedding of Jesse and Pamela Sargent (Goldblum's fiancée is a friend of the bride). Unsurprisingly, it went viral. Too bad he won't be in the upcoming sequel. (Goldblum's the one in the middle wearing the lighter grey suit.)
