If Hulk does ever get his own solo movie, I would love it would be anything similar to Agents of Smash. If you are not sure what Agents of Smash is, in a nutshell, Hulk and the Agents of Smash is where Hulk, Red Hulk, She Hulk, Skaar, and Rick Jones (a.k.a A-Bomb) go around fighting threats larger than The Avengers can handle such as Galactus. They also often travel through time and space but anyways...
Why This Won't Happen
Any form of Hulk stand alone movie can't happen until Marvel Studios buys back the full rights to the Incredible Hulk from Universal. If I were Universal I would just give back the rights because they won't make a Hulk movie and anyways, nobody wants to see THIS again
More Important Storylines
Also, if we are to get a Hulk movie, It won't be Agents of Smash because what the fans want is either Planet Hulk or something involving The Leader. If Hulk and the Agents of Smash are to get a movie, It would most likely be the 3rd or 2nd in the Hulk series.
So Many Hulks
Last but not least, with 3 rebooted Hulks, 2003, 2008, and The Avengers, it just wouldn't make any sense to people who aren't as connected to the news and updates of the ever-expanding MCU as the authors and viewers here at Moviepilot (No Offense).
Why it Could Happen
If Marvel does buy the rights back, and a new Hulk or 2 have already been made, Hulk and the Agents of Smash could easily happen.
Since Agents Of Smash is a Disney XD exclusive show, and Ant-Man gave us a "It's a Small World" easter egg, i'm pretty sure it's official that Disney also controls the MCU.
With General Thunderbolt Ross confirmed for Captain America: Civil War, many fans think that Red Hulk is going to take Banner's place in Cap 3. Which I would LOVE. If he does get implemented, that's 2/5 of the Agents Of Smash.
If AOS is going to happen after a Planet Hulk movie, then Skaar could already be in the MCU and 3/5 of the Smashers are ready to rumble.
Let me know what you think. Is Agents Of Smash a possibility for the MCU?
