Mary Louise Weller, the actress whose brief but memorable turn as a sorority queen in the 1978 comedy “Animal House” made her a fixture of one of the most quoted films in American pop culture, has died. She was 79.

No cause of death or other details were immediately available.

Weller arrived in Hollywood from a modeling career and landed the role of Mandy Pepperidge in “Animal House” - the poised, blonde foil to John Belushi’s marauding Bluto Blutarsky - at a moment when the film’s rude, anarchic humor was about to redraw the boundaries of screen comedy. Directed by John Landis and produced by Ivan Reitman, the low-budget Universal release opened in July 1978 and became a sleeper hit, eventually ranking among the highest-grossing comedies of its era and spawning a cottage industry of college-party imitations.

For a generation of moviegoers, Weller’s Mandy was the calm center of the storm: a sorority sister dating a preppy snob, caught between the genteel world of her campus house and the animalistic chaos of the Delta Tau Chi fraternity next door. She played the straight woman with a knowing glint, and her scenes with Belushi - particularly the cafeteria sequence in which Bluto silently mimics her every move - remain among the film’s most replayed moments.

“Animal House” was hardly a one-woman show. The ensemble included Belushi, Tim Matheson, John Vernon, Verna Bloom, Thomas Hulce, Stephen Furst, Karen Allen and Kevin Bacon, several of whom went on to long careers. But Weller’s Mandy occupied a specific place in the film’s comic architecture: the idealized coed whose eventual, reluctant embrace of the Deltas signals that the movie’s rebellion has won. She brought a sunny, unbothered quality to the part that made the joke land without mugging.

Born in New York City, Weller worked as a model before breaking into television and film in the mid-1970s. Her early credits included guest roles on series such as “Baretta” and “The Streets of San Francisco,” and she appeared in the 1977 television movie “The Amazing Howard Hughes.” After “Animal House,” she worked steadily through the early 1980s, with roles in the horror films “Blood Tide” and “Just Before Dawn,” the comedy “The Man with One Red Shoe,” and the television series “Falcon Crest” and “The Fall Guy.” She also appeared in the 1980 slasher film “Schizoid,” among other projects.

By the late 1980s and into the 1990s, Weller’s screen work slowed, and she largely stepped away from acting. She later pursued interests outside the industry, including real estate. In interviews, she spoke warmly of her “Animal House” experience and of the strange, durable afterlife of a movie that many of its cast members assumed would come and go.

“Animal House” itself is now enshrined in the National Film Registry and is regularly cited as one of the funniest American movies ever made. Its influence is visible in everything from “Revenge of the Nerds” to “Old School” to “Neighbors,” and its catchphrases - “Toga! Toga!” and “Fat, drunk and stupid is no way to go through life, son” among them - have never really left the culture. Weller’s contribution to that legacy was quieter than Belushi’s, but it was essential: someone had to stand still while the world exploded around her.

In a film built on excess, Weller provided restraint. In a film that treated women mostly as punchlines or props, she gave Mandy a flicker of self-possession - a woman who knows exactly how ridiculous the men around her are and chooses, in the end, to dance anyway. That small piece of comic grace is why her work still reads half a century later.

Details about survivors and funeral arrangements were not immediately released.
