Pepe Serna is downsizing…

The 71-year-old Mexican American veteran character actor and artist has joined the cast of Alexander Payne’s satire Downsizing, joining Matt Damon, Kristen Wiig, Christoph Waltz and Hong Chau, according to Variety.

The Paramount film, currently shooting in Toronto, centers on an Omaha man who joins the throngs of people undergoing a new process that reduces humans to a tiny fraction of their size. Then they move to one of the many communities of small people that are sprouting up around the world.

“It’s the smallest part I’ve ever had, four inches to be exact,” Serna said.

Payne is co-writing the script with Jim Taylor. The duo won an Oscar for best adapted screenplay for Sideways and collaborated on the scripts for Citizen Ruth, Election, Jurassic Park III, About Schmidt and I Now Pronounce You Chuck and Larry.

Serna is also one of the new members of the Academy of Motion Pictures Arts and Sciences, announced on Wednesday.

His career dates back nearly 50 years with credits including Scarface, American Me, Car Wash, The Black Dahlia and The Ballad of Gregorio Cortez.
