Ron Jeremy was a handsome enough fellow back when there were no VCRs, and I first saw him at the Strand theater in Binghamton. I think it was 1978.
The years have not been kind. He's starting to resemble Jabba the Hutt, and his on-screen persona is downright creepy, but in interviews he comes off as decent and intelligent. He's probably built up a lot of good will in the industry, and some actresses probably prefer working with his ugly ass.
Ron Jeremy looks like a creepy molester dad. That appeals to a certain demographic and since most porn actresses were molested as kids it helps them get into character.
Here's the real Ghostbusters sequal you wanted:
