It was 1981 when Harrison Ford and his bullwhip hit the big screen with “Raiders of the Lost Art.” Three years later the sequel “Indiana Jones and the Temple of Doom” came out, followed in 1989 by “Indiana Jones and the Last Crusade.” It’s been awhile, but the films still have a large following.

That’s what the United Boys & Girls Clubs of Santa Barbara are counting on when they screen the entire trilogy, twice, in a benefit Saturday at Santa Barbara’s Arlington Theater.

“Raiders of the Lost Ark” will be shown at noon and 7 p.m., “Indiana Jones and the Temple of Doom” at 2:15 p.m. and 9:30 p.m., and “Indiana Jones and the Last Crusade” at 4:30 p.m. and 11:15 p.m. Tickets are $10 for all three films, or $5 (adults), $3.50 (children under age 12) for individual showings. Free popcorn and soft drinks will be included. The Arlington is at 1317 State St. Call 962-0220 for more information.
