The other night I was startled from slumber by a most disturbing revelation: There may be an entire generation out there for whom the surname Belushi is primarily associated with the soul-calcifying sitcom According to Jim. Or that man’s shame-on-my-race, smokin’-blues boogie (bluegie?) outfit, Jim Belushi and the Sacred Heart Band. Folks, the reason that Jim Belushi isn’t currently scraping out the petrified nacho bin at Wrigley Field (in between skipping alimony payments) is the comedic momentum of his late, much-greater brother, John. National Lampoon’s Animal House is the best showcase for John’s genius, and if you haven’t seen his marvelous turn as a pustule or his eloquent, revisionist history (“Was it over when the Germans bombed Pearl Harbor?”) on the big screen, you’re missing out. Screenwriter Harold Ramis said that Animal House was “Adult Disney.” So come see the Platonic form of the Teen Sex Comedy with a drunken audience that has every line of dialogue memorized. Animal House screens tonight and Saturday, Nov. 30, at midnight at Visions Cinema Bistro Lounge, 1927 Florida Ave. NW. $5 ($10 on Saturday). (202) 667-0090. (David Dunlap Jr.)
