While quirky main characters like Philip J. Fry (Billy West), Leela (Katey Sagel), and Bender Rodriguez (John DiMaggio) are the reason why Futurama is so popular, side characters like Lars Fillmore (West) still make a big impression. Some of the most well-crafted Futurama episodes strike a perfect balance between including familiar faces and new characters who add some drama and intrigue to the time travel story. Season 5 includes four Futurama movies, and Lars plays a key role in Futurama: Bender’s Big Score. The movie is as humorous and clever as the rest of the animated TV series.
