Former Long Island representative and London Film School attendee Robert J. Mrazek has written and co-directed his first feature film, appropriately titled “The Congressman.”

Mrazek, 70, directed the film with Jared Martin, a filmmaker and actor known for his role as Dusty Farlow on the prime-time soap opera “Dallas.”

“The Congressman” stars Treat Williams (“The Prince of the City”) as Charlie Winship, a Maine congressman whose refusal to say the Pledge of Allegiance creates a media firestorm. The film also stars Elizabeth Marvel, of the Netflix series “House of Cards,” and George Hamilton, the ultra-tan actor from the comedy “Love at First Bite” (1979).

Mrazek, born in Rhode Island but raised in Huntington, represented New York’s 3rd congressional district on Long Island throughout much of the 1980s but retired in 1993 following accusations that he and other colleagues repeatedly overdrew their checking account funds at the House bank.

Mrazek was also the principal sponsor of the legislation that created the Library of Congress’ prestigious National Film Registry for the preservation of “culturally, historically or esthetically significant” movies.

“The Congressman” will screen on April 29 at Cinema Arts Centre in Huntington, as well as venues in New York City and Washington, D.C.
