Rough Theatrical Slate for 2010
Disney
The Sorcerer's Apprentice (Nicolas Cage version)
National Treasure 3: Edge of History
Gigantic (WDCA)
Eldest (sequel to Eragon)
Percy Jackson and the Olympians: The Lightning Thief (possible WDP/TCF dual-branding?)
Diary of a Wimpy Kid (possible WDP/TCF dual-branding?)
Wall Street: Money Never Sleeps
Sounds like a good slate for Disney. Although, I'd have Wimpy Kid as a WDP branded film, while Percy Jackson is a dual-branded feature.
Paramount
Avatar: The Last Airbender
Despicable Me (Illumination)
The Chronicles of Narnia: The Voyage of Dawn Treader (Paramount/United Artists dual-branding)
Hot Tub Time Machine
Thundercats 2
Legally Blonde 3
Ghostbusters 3
Clash of the Titans (remake)
Jackass 3D
Paranormal Activity 2
MGM anime dub to be named later
Of these, A:TLA, Despicable Me, Thundercats 2, Ghostbusters 3, and the upcoming MGM anime dub excite me the most.
Peacock
The Phantom (Universal; part of the King Features universe)
How to Train Your Dragon (DreamWorks)
Shrek Forever After (DreamWorks)
She's Out of My League (RKO)
Megamind (DreamWorks)
Harry Potter and the Deathly Hallows - Part One
Little Fockers (Universal)
MacGruber (RKO; SNL Studios)
I would consider delaying Megamind to 2011, so that it doesn't fall victim to Despicable Me's success.
Touchstone
Toy Story 3 (Pixar)
Yogi Bear (Seth Rogen version)
May I ask what Seth Rogen had in mind with Yogi Bear?
Columbia-TriStar
Red
Jonah Hex
The Back-Up Plan
Is Red a movie based on Red Hot Riding Hood? I don't know what it is otherwise. Maybe a gritty retelling of the original fable, but not much else.
Luxor
Sex and the City 2
Lionsgate
Twilight Saga: Eclipse
Saw 3D
Warner Bros
Predators
New Line Cinema
Goosebumps (With Chris Rock as Slappy)
The Spy Next Door (Golden Harvest)
Pretty paltry lineups for these studios.
TBD
Kick-Ass (I don't know who actually owns Kick-Ass IOTL, so I might assign this one to maybe Luxor unless it would fit better somewhere else)
In our timeline, it was published by Icon Comics. Assuming it's the same label as IOTL, make it a Fox entry.
Prince of Persia (I don't know who got the rights after Broderbund folded IOTL. I have a feeling Prince of Persia came with Carmen Sandiego to Disney in 1999 ITTL but please remind me if that wasn't the case).
Ubisoft bought the property in 2001, so if the selling to Disney were to happen two years sooner than that, Prince of Persia would be a Disney property as you assumed.
The A-Team
Knight and Day (Even if this one wasn't that great IOTL, I still like the clever title)
Grown Ups
Inception
Ramona and Beezus
The Other Guys
The Expendables
Scott Pilgrim vs. the World
Vampires Suck
Nanny McPhee
Machete
Alpha and Omega (Made by Crest Animation IOTL)
The Social Network
Secretariat
I Spit on Your Grave
The King's Speech
Gulliver's Travels (Jack Black version)
The Last Song
Get Him to the Greek
I think you can put most of these to their OTL distributors, but maybe have Ramona and Beezus under the Disney label.
