Sasha Barrese, who starred in The Hangover and The Hangover Part II, has signed on to return for The Hangover Part III. She reprises her role as Tracy, who got married to Justin Bartha’s Doug at the end of The Hangover.

It isn’t clear how she will fit into the story line of this upcoming comedy sequel, largely because there’s been no plot details for the movie released, other than the gang will return to Las Vegas. She will not be the only familiar face returning for the final chapter. Along with The Wolf Pack (Bradley Cooper, Zach Galifianakis, Ed Helms, and Justin Bartha), Ken Jeong, Mike Epps, Mike Tyson, and Heather Graham are all back.

Todd Phillips is directing from a screenplay he co-wrote with Craig Mazin. Film is scheduled to begin this fall. (Source: Variety)
