Backstreet Boy Brian Littrell is going solo for an indie movie soundtrack.

Brian will sing the title song for the film "Olive Juice". He also co-wrote the song. The Backstreet Boys' sugary sweet song "The Perfect Fan" will also appear on the soundtrack, MTV reports.

The movie stars Brian's wife Leighanne Wallace and is a romantic comedy that revolves around a pet shop. Lil' Tyk Thomas, Brian and Leighanne's Chihuahua, which was kidnapped by a fan last summer, also stars in the movie.

In addition to singing for the film, Brian will make a cameo appearance in "Olive Juice" along with his Backstreet pal AJ McLean.

Brian will briefly grace the screen as a horse-drawn carriage driver, while AJ can be spotted acting as a DJ in the film.

"Olive Juice" was filmed in Orlando. It will premiere on Feb. 2 in Orlando and run for a short time in Florida before it comes out on video.

There's no word yet on whether the movie's soundtrack will be released as a CD, but it's possible that Brian and Leighanne could put it out through their company, Brileigh Productions.
