Tommy “Tiny” Lister, best known for his roles in The Dark Knight and the Friday film series, has died at the age of 62.

While he had not tested positive for the novel coronavirus prior to his death, Lister died on Thursday after exhibiting “COVID symptoms” for a week, his manager Cindy Cowan tells PEOPLE.

“He was a gentle giant and one-of-a-kind,” she says. “A man that’s like been a brother to me for 20 years.”

The actor was scheduled to work on a movie over the weekend, but had canceled on Friday, according to Cowan.

“He was just really complaining, but he was too weak to go to the doctor,” she says.
