There’s been scuttlebutt about Sorbo for years now. A co-worker alledged he’s a sexual harrasser, his publicist sued him for non-payment, and rumors say he drove off the showrunners of Gene Roddenberry’s Andromeda because his role wasn’t big or important enough for him.
So yeah, by all accounts, Sorbo’s an “actor” whose ego was/is far bigger than his talent (and his mouth’s bigger than his ego.) It’s no wonder so many people don’t want to work with that problem child. 
And Iolaus was always more interesting to me than Jerkules anyway. 
The character was more complex, and the actor (Michael Hurst) had mad acting and directing talent.
