The clip, shared on Wednesday by Bidenâs campaign, features Hamill watching and reacting to some of Trumpâs past media appearances.
âI donât know about you, but after four years of this administration, Iâm exhausted,â the actor says in the beginning. âIâm getting ready to watch some videos of him, and if ever the Force would be with me I need it right now.â
Hamill is then seen watching a clip of Trump refusing to commit to a peaceful transition of power should he lose the 2020 presidential race.
âThis is so frightening, because he said âThe only way I can lose is if itâs a rigged election,'â Hamill says, paraphrasing Trump. âSo heâs setting up the idea that unless he wins, itâs fraud. Thatâs truly dangerous.â
After a couple more clips play, Hamill says of Trump: âThis guy couldnât be president of the PTA [parent-teacher association]. He is easily the worst president ever.â
Hamill then urges voters to cast their ballots, telling them: âVoting is going on right now and everything is on the ballot, and we canât be complacent. We have to fight until the end like weâre double digits behind.â
The actor, who portrays Luke Skywalker in the Star Wars film series, has criticised the Trump administration and other Republicans in the past.
He recently labelled Senate majority leader Mitch McConnell Â âpure evilâ for laughing off questioning about coronavirus aid during a debate.
