I saw this in my recommendations. Corey Haim talks about looking up to John Ritter as his idol. He wanted to work with him. He gets a few things wrong. Ritter never worked as a stunt man or went to Vietnam. Maybe he was thinking about Richard Kline who served in Vietnam during the Vietnam War as a lieutenant.

This is from around the time Skin Deep was released. It starts at about 9:10.

He also mentioned looking up to John Ritter in the 1989 documentary Corey Haim: Me, Myself, and I. It starts at about 7:20.

There is no doubt in my mind he admired Ritter, Its obvious he never met him up until the time of this interview. The only facts correct were he knew Ritter was on TC and Skin Deep was just released in 89. Unfortunately in the end
Haim was taking 86 pills a day of different meds, possibly that let to poor misrecollection.
