Okay, I think I fainted right around when Jason Segal said "It's time to light the lights."
I am officially in love. Oh, and Walter talked! Oh, and Robin! And Rizzo! And Pepe! And a random robot!
Some awesome things I noticed, just to organize all my thoughts.
0:10- ELECTRIC MAYHEM BUS!!!
0:12- Is that Walter's voice? I think it is!!!!!
0:18- Holy Crud.
0:20- Where I peed my pants.
0:25- Wow, haven't seen this room before!
0:30- Wanda IS with Wayne! First time we've seen her!
0:45- Is this breaking the 4th wall? I think IT IS!!!
0:47- Are these The Moppets?
0:53- What's with the big brawl?
0:56- Bobo fencing Chris Cooper? Again, LOVE IT!!!!
0:59- This must be Kermit's house
1:00- Walter again!!!!!
1:07- Wait, does that fence say "K&P"? Is it possible that Miss Piggy used to live with Kermit?
1:13- Only thing in this trailer that I don't love.
1:24- I don't know what's more awesome, Kermit's speech, Rizzo, Pepe, Robin, or the random robot.
1:28- Rowlf at the PIANO!!!!!!!
1:32- This must be the Vegas showgirl number Chris Cooper was talking about.
1:36- MAHNA MAHNA!!!!!!! And the random robot again!!!!!!!! And he's driving!!!!!
1:48- Yes Floyd, yes I do. Wait, what do you mean, that was a rhetorical question?
1:50- Ah, Gonzo, how I've missed your wacky tricks!
1:53- I think this must be during the aforementioned Vegas showgirl scene. It looks like it takes place in a Hard Rock Cafe.
1:54- I just peed my pants again.
1:56- Smalltown, USA?
1:59- Peed my pants again.
Lots of secondary characters in this one. In addition to the ones already mentioned, I also spotted Carl, the Afghan Hound, Luncheon Counter Monster, the Mutations and the Blustering Bellowpane Monster. I also spotted Trumpet Girl in the orchestra pit when Walter bows on stage and Mahna Mahna, the Snowths and the Geri & the Atrics drummer in the arches.
Hope there's many more minor character pop-ups to come in the film. Still keeping my fingers crossed for Lenny the Lizard, Boppity, Gloat, Baskerville, Muppy, Rover Joe, T.R., Catgut, George, Mildred, Pops, the one-sentence birds, the jugband and others.
