Even when I see Elrond in LotR, that's actually just Agent Smith in a funny costume.

Vince Vaughn as Vince Vaughn in everything.

After Miracle Workers, Guns Akimbo and especially Weird: The Al Yankovic Story, Daniel Radcliffe is so much more than Harry Potter to me. He's got this almost Nicolas Cage-y vibe now

Frodo, even if I was impressed in the movie Hooligan.

Robert Downey Jr. as Tony Stark, and Daniel Craig as James Bond.

Niel Patrick Harris will always be Barney Stinson.

Seeing Wayne Knight in Jurassic Park, wondering why Newman is there

Jason Alexander.

Rami Malek will always be a hacker

I liked Bradley Cooper but after watching American Sniper I can't see his face anymore without seeing the smug visage of imperialist murder.

Laurence Fishbourne will always be Morpheous to me

I like how Robert Pattinson has done quite a few weird roles that Twilight isn't always the first thing I think of with him lol

The entire cast of It's Always Sunny in Philadelphia. Danny Devito may have decades of work under his belt, but he'll always be Frank Reynolds to me.

That Blackberry movie that Glenn Howerton was in was decent, but I could not take Bald Dennis seriously.

Tom Cruise is just Tom Cruise to me, I never feel like he disappears into any kind of role - he's just Tom Cruise pretending to be someone else who happens to look and act similarly to Tom Cruise.

With one exception, that being Les Grossman from Tropic Thunder 😆

Kevin Spacey will always be Kevin Spacey. I can't watch him act and see anything else but Kevin Spacey.

Adult Danielle Radcliffe I don't really think "that's Harry Potter". Probably because the beard.

Wesley snipes is blade though.

RDJ just is iron man at this point. I saw him in Oppenheimer and was genuinely distracted by it.

Sorry Aubrey Plaza, you will forever be an intern

Christian Bale, Patrick Bateman.

Ryan Reynolds will always be Ryan Reynolds

A lot, but ones that stand up mostly (except few Polish ones which i won't mention because you wouldn't recognize them anyway) are Sean Connery as Marko Ramius, Patrick Stewart as Jean-Luc Picard and Tom Cruise as piece of wood.

Linda Cardinelli is always Lindsay Weir.

Jeff Bridges will always be The Dude.

Heath Ledger will always be the Joker.

Mr. T will always be Mr. T from the A-Team to me.

I can't hear Richard Horvitz without thinking of Invader Zim. He does a ton of random voices in the more recent Ratchet and Clank games and it's very distracting.
