Truly an actor's actor. Bravo!

I don't know anyone with the style of Pleasence.

It sort of depends on what period of Pleasence's career we're talking about. In terms of the years when he provided support in more mainstream motion pictures, I would say Stellan Skarsgrd serves a similar role today.
If you get into his latter day professional horror guest star period, it's definitely Robert Englund, who rarely carries a horror film but always gets his name above the title.

Strangely enough after watching Will Penny, Donal Pleasence vaguely remindered me of Charlie Day and Bobcat Goldthwait.
Other than watching movies, I'm a quiet 1908and modest indie game developer. Blossomsoft Games.

Taylor Lautner will be there in a few years. Give him time and the right roles.

The Ben Kingsley comparison is pretty good. Sir Ben has certainly done some sh*t as of late, but he's ALWAYS good.
I love to love my Lisa.

Anthony Hopkins is now getting into "Pleasence" territory..He and Ben Kingsley are both marvelous character actors given the right material. Hopkins will be playing Alfred Hitchcock and I can't wait to see it.

I wanted to write sh it ti es t, but imdb wouldn't let me. Now I did anyway.

Yep, definitely agree about Ben Kingsley. Not because he's bald, but for his strange variety in movies. Kingsley appears the greatest films and the beep crap, but always earns good reviews, even if the film doesn't.
Same with Donald Pleasance.

I once heard Ben Kingsley described as "the new Donald Pleasence".

No one can compare to Donald Pleasence period!!

Zip.. no one.
Had to add an edit that I didn't when I posted this comment..
Yes he was excellent.. but keep in mind..
That as far as character actors.. he was for many years relegated to doing not A class ones..
You take Walter Brennen.. this guy was a character actor supreme..and so where many others.. but the great Char.. actors started dying off.. and not enough to replace them.. so eventually.. Donald move from 'B' to 'A'.. nice he could manage to do so that's the way it was..

Anthony Hopkins

Stanley Tucci & John Lithgow from that top of my head.
Its that man again!!

Sadly no one that I can think of.
