Or, more accurately, Harold Perrineu? Has the actor left the show? Is he shooting a movie or starring in a Broadway play? Or is he just relaxing, sipping beer and cashing his Lost paychecks while the writers figure out if Michaeal comes back with WAAAAALLLLTTT or not?
(Apologies if this has been covered before. I haven’t slogged through the multi-page Lost threads to see if this has been discussed.)
He went after Waaaaaaaaaaalt. We never see him again, but when Jack and gang meet up with bearded guy, bearded guy tells them that Miccheal is safe, but will never find Walt.

He’s, uh… lost.
Okay, guys, step off Craphole Island and into reality for a second. 
I’d like to know if Perrineau is on the shelf or off pursuing other interests.
I have not heard that he is pursuing anything else and that his absence is only due to the writer’s whims. Granted I am not deeply entrenched in Lost actor and actress news, but I do watch headlines and haven’t heard about him leaving the show or anything.
So, since he’s under contract, he gets a nice paid vacation for a month or so? This acting gig is quite the thing, isn’t it?
Not only that, it’s a paid vacation in Hawaii. The IMDb lists him as possibly being in production on something called Random Acts of Kindness, but there’s nothing definitive on there.
I don’t know if they do all their filming sequentially but he might be with another filming crew working right now, he may not be actually on vacation. Granted with episodes where he’s missing, he’s probably got a lighter work load than others.
Sometimes actors are only under contract for a certain number of episodes in a season. So they have to be put on ice for a while if they’re used too much. Don’t know if that’s the case here, but it wouldn’t surprise me given the size of Lost’s cast.
I heard that Waaaaaaaalt is under a pay per episode contract… so that poor kid is going through puberty AND not getting paid.
I honesty doubt we’ll see much of Walt on the show again…or atleast the kid actor who plays him.
It’s pretty common for actors in shows with large casts to be out of the picture for a while. Mr Eko only had a quick reaction shot in last week episode. He hasn’t left the group and he only had 10 seconds more air time than Michael. I haven’t heard anything about him leaving. I’m sure if he wanted out they would kill him off dramatically.
