BEIJING, April 24 (Xinhuanet) -- Comic actor Chevy Chase in an authorized biography said he is unable to forgive his deceased mother and stepfather for childhood beatings and psychological abuse, the New York Post reported Monday.

"I always turn to it in my mind," Chasesaid. "I'll never forgive them. At their graves I didn't. It was too hard for me. You would think a grown man could shake it off, as the coffin was lowered, to say, ‘I forgive you.’ I don't forgive."

One of the first members of the "Saturday Night Live" TV sketch comedy troupe and the star of such films as "Fletch,""Caddyshack"and National Lampoon's "Vacation," Chase told writer Rena Fruchter he lived in fear of his mother, a concert pianist who suffered from depression and panic attacks.

"She would say to me,‘Ten lashes on the backs of your legs every day for a week at 5 p.m.,'" Chase says in the book, to be published by Virgin Books USA next month and titled, "I'm Chevy Chase ... And You're Not."

"How can you hold on to that kind of anger against your kid?" Chase says. "I knew I was a ‘bad boy,’but I didn't know that everybody wasn't punished in the same way I was."

Chase, 63, told Fruchter that his mother's second husband also subjected him to "emotional and physical abuse that sometimes bordered on torture."
