Making their debut at the tender age of nine months, both sisters were used in rotation to portray Michelle Tanner, the baby of the "Full House" household. The acclaimed family sitcom was a staple show of ABC, running for eight seasons and turning out future star John Stamos ("ER").

Appealing to the opposite end of the holiday sphere, "Double, Double" featured the Olsen twins attempting to free their kindly old aunt from the spell of her wicked twin sister. Cloris Leachman ("Young Frankenstein") played both aunts, and the film also starred Eric McCormack ("Will & Grace") and Phil Fondacaro ("Willow").

The modern remake of Hal Roach's "Our Gang" comedies showcased the talents of several young actors, including Travis Tedford ("Slappy and the Stinkers"), Bug Hall ("Honey, We Shrunk Ourselves"), and Kevin Woods ("The Brainiacs.com"), and was largely a success with critics. Though they played small roles, it was the Olsens' first time to be featured in a theatrically-released movie.

Kirstie Alley ("Cheers") and Steve Guttenberg ("Police Academy") co-star in the twins' first-ever headlined theatrical feature about two identical opposites who try to bring their two guardians together to stop a fateful marriage. Though the film has achieved cult status among fans, it was bashed by critics upon its release; it would be years until the Olsens would be seen in theatres again.

The twins' first entry into an extended stay in the direct-to-video market featured them as Los Angeles sisters trying to get their widowed father to date by posting an ad on a giant billboard on Sunset Boulevard. By now, the Olsens were entering their teens, and were slowly beginning to separate themselves from their "little girl" image by featuring adolescent romance and dating as plot points.

When a tournament lands two soccer-playing sisters on opposing teams, they secretly attempt a switch to even out their mismatched squads. Co-stars Eric Lutes ("So Little Time"), Kathryn Greenwood ("Wind at my Back") and features a cameo by US soccer star Alexi Lalas.

After her sister Chloe's Model United Nations team loses a member, bad-girl Riley must jump in as a replacement as the team enters a London-based competition to represent a country they are unfamilliar with - England. Also stars Jesse Spencer ("House M.D.") and Rachel Roth ("Titus").

Saddened that they didn't go to Hawaii with their friends, two sisters on winter vacation think twice upon catching wind of a comely young worker (Austin Nichols, "The Day After Tomorrow") at their Bahamas resort...yet the fun turns fickle when a wooing-contest is iniated by a jealous young heiress and the girls cross paths with a dangerous smuggler.

The twins and a group of their friends are headed for the 2002 Winter Olympics in Salt Lake City in their new birthday present, a Ford Mustang. On their way, they encounter plenty of adventures, and even a bit of romance... Also stars Billy Aaron Brown ("Jeepers Creepers 2") and Heather Lindell ("Days of Our Lives").

After two sisters - total opposites besides appearance - are placed on the same team of a reality TV show by scheming producers, they must try to get along for the sake of winning the grand prize of college scholarships. Also features Brian Skala ("Just Deal"), Sarah Bastian ("The Work and the Glory" 2-3), and Joe Michael Burke ("Hollywood Safari").

Starring in their first theatrical film in almost nine years, the Olsens portray a pair of couldn't-be-less-alike sisters who must avoid a criminal piracy gang and a school truancy officer as they navigate through New York en route to a scholarship competition and rock video shoot. The film was a large dissapointment, drawing heat from critics and failing to make back its $30 million budget.
