Los Angeles: Veteran actor Pepe Serna has joined actors Matt Damon, Kristen Wiig, Christoph Waltz and Hong Chau in Alexander Payne’s satire “Downsizing”. The film, currently being shot in Toronto, is 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,” variety.com quoted Serna as saying. Payne is co-writing the script with Jim Taylor, with whom he 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, which was 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".
