Mad Men alum Adria Tennor has joined the cast of D-Train.

D-TrainJames Marsden and Jack Black star in the film, the story of Dan (Black), the head of a high school reunion committee, who  travels to Los Angeles to track down the most popular guy from his graduating class (Marsden) and convince him to go to the reunion.

Tennor, whose other film credits include The Artist and You Don’t Mess with the Zohan, plays Wendy, the most popular girl in high school. She’s thrilled to see Dan’s wife Stacy (Kathryn Hahn) at the reunion, but has absolutely no idea who Dan is.

D-Train, written and directed by Andrew Mogel and Jarrad Paul, is currently filming in New Orleans.

Tennor, who played Joyce Darling on AMC’s Mad Men, next appears in John Schneider’s Smothered; she is also the proprietor of the restaurants Barbrix and Cooks Country Restaurant.
