Two of Travis Bacon's bands (Terror Level Red, Grudges) are in the queue, but are orphaned for now.

Charlie Sheen is now in the queue.

Terror Level Red and Grudges have been un-orphaned.

Jeff Bridges is in the queue now.

Scarlett Johansson is no longer orphaned.

Kevin Costner is no longer orphaned.

The late Bill Paxton and Miguel Ferrer are also in the queue.

Saw this from Ben Stiller but doesn't look like he's easily connectable:

Dennis Quaid and Jeff Goldblum have both entered the db in recent days.

Bryan Cranston and Kristen Wiig are both in the queue.

If "Sausage Party Case" is a band, then lost of other actors can get in as well:

Matt Berry (UK) is now in the queue. Year Of The Rabbit was the best thing on TV last year.

Berry only plays one character yet in Toast, Rabbit, What We Do In The Shadows or House of Fools, it always works...

I need some help getting River Phoenix in, he's on this, in Aleka's Attic, together with his sister Rain:

Rain has played in The Causey Way. She's not on the two albums of them I have queued, but she might be on the EP's/singles/compilations, of which I haven't found proper credits yet.

edit: The scans for the single are a bit unclear, so I can't really see who's playing bass on the Aleka's Attic song "Where I'd Gone". It's Michael Pe...??, he also gets a credit for mixing the song.

edit 2: Checked all the releases, but Rain doesn't seem to be on any one of them. The only Causey Way tracks that are uncredited and not released on any album or EP are on this compilation:

Just queued up Michael Chabon for his early Pittsburgh band The Bats.

James Marsters of Buffy/Angel fame (still two of the best TV shows ever made) is in the queue now but need to confirm I'm not conflating two entirely different Aaron Andersons to get him in.

Not the same unfortunately

Thanks Harry. I've disambiguated them and will see if I can get anywhere with connections off Fictionist.

Charlie Heaton (Jonathan in Stranger Things) is now in the queue.
