Peacock released a trailer for Gary Wednesday that shows Coleman grappling with regret.

"If someone had of told me my life would have been like this early enough where I could have got out, I would have got out," he said in the snippet.

In addition to that betrayal, the trailer spotlights health and marital issues.

The documentary will feature interviews with estranged family and former colleagues.

"Viewers will get insight into Coleman's lifelong illness and depression, his financial troubles, tumultuous marriage, and his heartbreaking demise," an official synopsis reads.
