Underrated/underseen Actors?

That is a damn good call, always been a fan of Ironside, even though it has caused me to waste money and time, sitting through one crappy movie, after another.
But the man always deliver the goods. 
I guess what you bring up, about his intimidating look and performances, sure killed off getting more pleasant and heroic parts, and even in the few (I have seen) where he has had a starring/leading role, he comes of as not the most "friendly" or "typical" leading man, but then again, I kind of like that. He has his ways of doing it, and I liked his role in the sci-fi/post apocalyptic western Neon City (1991).

That one, I really want a DVD/Blu-ray of. Another rare title, which I only picked up, cause of Ironside, was the cheap and boring sci-fi/triller Mindfield (1989), which I think were some Canadian release, and where the artwork, sure tried to benefit from Ironside and his earlier role in the cult-classic Scanners (1981). But beside that, there is not much to go on, as Mindfield was very poor, and boring. Still, it did feature a ridiculous sex scene (or so I remember it) where Ironside and the lovely Lisa Langlois.

Would love to hear if anyone has any good recommendations of more dominant/bigger parts in films which actually are not all that terrible/bad.
