Elf is absolutely his 2nd most well known role. I don't think it is even close at this point. Nobody under 50 has seen Brian's Song. Misery is a really good movie and a nice solid $60 million hit. Elf made $250 million, spawned a Broadway musical and is on TV/streaming non-stop for about 2 months every year. It is firmly in the top 5-10 Christmas movies of all time which means it will live forever and be not only a movie but an annual tradition for millions of families.Honestly, because my kids and wife absolutely adore Elf (and I do, too, actually), this is what I've seen him most in, and really think he's great in. Sure, Misery and Brian's Song are probably "better" movies, but Elf is kinda turning into a Christmas classic - if it hasn't already - and like you said, younger folks probably don't even know of those other flicks.
In any case, God bless his soul! Great actor.
