A quick look at the Britney Spears filmography on IMDb will show that the bulk of her TV and movie acting credits are in the role she was born to play: herself. But she has played other characters in a handful of projects, starting with the 2001 sports action comedy “Longshot,” produced by pop impresario Lou Pearlman, who briefly managed Spears during the early part of her music career. Pearlman appears to have called in all his celebrity favors to populate the film with cameos, as Spears is joined in the role of “Flight Attendant” by famous faces like Dwayne “The Rock” Johnson, Erik Estrada, Kenny Rogers, and all the members of N*SYNC. Spears also joined a host of other celebrities in voicing characters in two animated Christmas films: 1999’s “Hooves of Fire” and 2002’s “Robbie the Reindeer in Legend of the Lost Tribe,” voicing the reindeer Donner in both shorts.
Spears’s proper big screen debut came the following year, with 2002’s “Crossroads.” Spears plays Lucy, a teenager who finds herself on a great American road trip with friends played by Zoe Saldana and Taryn Manning. While Lucy eventually takes up a music career and seems to share some similarities with Spears herself, it does count as a separate character for our purposes.
The pop star’s other two acting roles of note were on two popular sitcoms. She played Amber-Louise, the unwanted co-host of Jack’s (Sean Hayes) revamped talk show, on a 2006 episode of “Will & Grace” entitled “Buy, Buy Baby.” She made another guest appearance on two episodes of “How I Met Your Mother” in the role of Abby, one of Barney’s (Neil Patrick Harris) old conquests who takes her revenge.
