A scowling Mark Hamill pokes fun at his performance in "The Force Awakens" in the announcement video for the new "Star Wars": Force for Change campaign.

Prompted by Lucasfilm President Kathleen Kennedy, the franchise veteran remains motionless before saying, "Oh, I'm sorry, I have dialogue? I'm used to just staring intensely."

Launching today, the month-long campaign will match donations from "Star Wars" fans up to $1 million, with the proceeds going to benefit the U.S. Fund for UNICEF in support of UNICEF Kid Power, American Red Cross, Boys & Girls Clubs of America, and Make-A-Wish.

Every fan who donates $10 or more before 11:59 p.m. PT on May (May the Fourth) will be entered for a chance to win an all-expense paid trip to Ireland, including Skellig Michael, where the finale scene of "The Force Awakens" was filmed.

To date, Force for Change has raised more than $10 million for charities.
