Actor Mark Hamill, best known for his role as Luke Skywalker in the Star Wars series, on Wednesday explained how he had suddenly found himself pulled into the political arena.

The reclusive star opened a Twitter account at the urging of his daughter. Hamill had been sending out innocuous tweets about his preferences for jam.

But after the presidential debate last week he was so "outraged" that he publicly blasted GOP hopeful Mitt Romney. In a tweet, Hamill described Romney as a liar and "snake-oil salesman" who needed to be defeated.

"I debated in high school. If you told things that weren’t true or just made things out of whole cloth, you were penalized. It’s too bad they don’t apply the same standards to presidential candidates as they do to high school students," he told Current TV host Cenk Ugyur.

Hamill said he was worried about low-information voters, who might not be aware of Romney's penchant for changing his positions.

"I would cast this guy as the president in a heartbeat," he added. "He's got the hair, he's got the stature, he's got the wardrobe, but I just cannot believe a word he says."
