I don't think it's the be-all, end-all of fame metrics, but YouGov has a 'fame ranking' tool.
Sebastian Maniscalco shows as the 587th most popular and 575th most famous contemporary actor
For comparison
Regina Hall was 249th most popular and 287th most famous contemporary actress.
Amy Schumer ranked as the 69th most popular and 24th most famous TV personality
Wanda Sykes ranked as the 17(!) most popular and 77th most famous TV personality

Clearly he's not in the same category as those other hosts

I like Robert Downey Jr. as an actor and I’m incredibly impressed by his redemption story in life but he always comes off as a pompous jerk in real life. Maybe acting self-important is part of his schtick but I’ve grown tired of him channeling a Tony Stark attitude in real life.

How about thinking somewhat out of the box and getting someone like Daniel Radcliffe as host?

Dave Bautista. Not positive how it'd turn out but he'd definitely give it his all.

I'll do it.

Seriously, I'll be available that winter, I'd be glad to do it. And I think I would be good at it.

I'll do it.

I think James Corden has a lot of free time now.

Let's give Dave another shot at it, just in time for the 30th anniversary of his last Oscars hosting gig.

Where do you stand on having the crap slapped out of you?

Nothing that I posted disagrees with any of that.

...I mean... I mean, if it's tastefully done... and for charity...

Nope, we are in agreement, he's worked in things but he's not very famous outside of the stand-up crowd.

An analogy that occurred to me : Being Stand-Up famous is kind of like being EDM famous. There are EDM acts that are hugely popular within that world, like Illenium and ODESZA that sell out huge venues, but are just about unknown outside of that world. Somebody called Anyma has six sold-out shows coming up at the Sphere for New Years. These sorts of groups (? Artists?) are such a huge draw for people who are into that sort of thing, but pretty much unheard of in popular music until the release a pop single with someone like Coldplay or Sam Smith.

Stand up is kind of like that. Ali Wong was a huge stand-up draw for years in that world, but needed a Birds of Prey, an Always Be My Maybe, a Beef to become a household name.

Ash coming home from work :

To be a little fair to Jeff though, Sebastian Maniscalco isn't really that different from John Mulaney, whose public output has also mainly been comedy specials. He's just been around a little longer and done more of them. I still don't think he's a good option for hosting, but given that Mulaney was offered the gig, it wasn't a completely outrageous suggestion.

I know someone said Hugh Jackman, but no suggestion of Jackman and Ryan Reynolds co-hosting?

The difference is that John Mulaney is very, very much Hollywood famous. Maniscalco certainly has the claim to fame in the world of stand-up comedy, but Mulaney is just a flat-out celebrity at this point.

After the recent update in the Bill and Ted thread, my first thought was, “How about Keanu Reeves and Alex Winter as hosts”.

Mulaney would have been my first choice but either of these combos would be superb.

ABC won't hire the host of CBS's late night show to host the Oscars.

Letterman was 30 years ago when ABC did not have its own late night franchise, and Dave was the new king of TV.

Hugh Jackman would be the ideal choice but did he lose interest or the desire to host awards shows since it has been awhile since the last hosting gig?

Poehler and Fey would be great but maybe they declined in the past and not interested?

I know Bill Burr and Marc Maron would never be considered though Maron interviews a lot of celebrities and is a movie fan and he is working on a show with Owen Wilson and did some movies and he is working on a movie later this year and his profile might be getting bigger.

He also could throw in some political jokes if you need that.

Apparently, they are "at the top of the wishlist": https://www.intouchweekly.com/posts/...ish-list-excl/

They're looking at a host-less show with more star segments.

ooo . . . stunts

I'm glad Kimmel passed on it. Seems like he's been hosting for a while now. (Maybe it's just me though)

My choices

I predict that Megaopolis and Joker 2 fight it out for the most nominations.
