After going through the decimated Alberta neighborhood in Tuscaloosa, Sheen said Press he was working with officials to organize a benefit. He said a date has not been set.
"I want some money, hope, faith and healing to the area," said Sheen, the former star of the CBS sitcom Two and a Half Men.
Sheen was fired from the show in March and has been in a bitter dispute with executive producer Chuck Lorre and Warner Bros. Television. Since then, he has launched a stage tour that has captured attention.
The actor, wearing a University of Alabama baseball cap, said he decided to visit after receiving an invitation via Twitter from a University of Alabama student. David Harris, of Mobile, had asked in a tweet April 30 if he would be willing to perform a relief show in Alabama, Sheen said.
Sheen spent the day in Tuscaloosa meeting with storm victims and first responders.
At each stop, he was swarmed by people asking for autographs and photographs. Sheen also stopped by a Kmart to buy flashlights for some of the thousands of people still without electricity. He paid the $324.07 tab and brought them to a relief center amid loud cheers and applause.
