Movie Crossovers For Both G.I. Joe/Transformers And Pacific Rim/Godzilla Being Considered

If there's one thing that will guarantee big bucks at the box office, it's getting many well known actors and characters into on big action movie, a formula proven very successful by Marvel's The Avengers just last year. With the release of G.I. Joe Retaliation just last week, a third film has already been announced to be in the works after the sequel scored big at the box office, but it seems another project may also be in store for the franchise. Now it seems producer Lorenzo di Bonaventura is considering putting two of his properties; G.I. Joe and Transformers together in one film. In the meantime, Guillermo Del Toro, director of this summer's Pacific Rim, is also contemplating the idea of doing a crossover film with Gareth Edward's new Godzilla reboot. But will we be seeing the stars of these films all teamed up in one movie, and what type of plot will they use to get all these characters together? 

The G.I. Joe/Transformers crossover seems to be the much less surprising of the two, as both franchises are created by Hasbro, produced by Lorenzo di Bonaventura, and are big money makers for Paramount Pictures. With Michael Bay's Transformers 4 set to be release summer of 2014 without Shia LaBeouf's Sam Witwicky leading the cast, it's likely the film could be focusing more on the NET division of the military from the series. It's still unknown just who Mark Wahlberg will be playing in Transformers 4, but many have assumed he will in fact be playing a soldier in the NET division, which is further supported by cats member Tyrese Gibson returning as NET soldier "Epps" for the first three films.
With Dwayne "The Rock" Johnson now practically leading the G.I. Joe series as Roadblock, if this crossover film really does come together then we'll be able to see The Rock reteaming with Wahlberg, as they'll both be starring in Michael Bay's Pain and Gain. Now depending on how much chemistry the two have on Pain and Gain, it seems a safe bet that Paramount is really considering the cash advantages of reteaming both Wahlberg and Johnson, especially if Michael Bay also directs the crossover film. Teaming up the Joes and the NET soldiers against a common threat lead by both Cobra Commander and Megatron seems like the type of plot we can expect to see if the crossover film goes through.
Now as for the other giant mechanical robots hitting the big screen this summer in Pacific Rim, director Guillermo Del Toro has brought up the possibility of a crossover film. Just a few weeks ago Gareth Edward's Godzilla reboot rolled into production for a 2014 release date. Godzilla also seems to have a very military based film, pitting the army against the giant reptile in an all out war. The film already has a very impressive cast which includes Elizabeth Olsen (Martha Marcy May Marlene), Ken Wantanabe (Inception), Bryan Cranston (Breaking Bad), David Strathairn (The Bourne Ultimatum), Richard T. Jones (Super 8), Sally Hawkins (Happy-Go-Lucky), and Aaron Taylor Johnson (Kick-Ass) in the lead role of a soldier in the army fending off Godzilla.
While Gareth Edward's still hasn't commented on the possibility (We wouldn't expect him to since he's currently focused on the movie at hand), it isn't too far fetched of an idea. Both properties are being produced by Legendary Pictures, and Guillermo Del Toro made Pacific Rim in the first place to acknowledge his inspiration from Japanese monster films, most notably the original Ishiro Honda Godzilla film. The plot of Pacific Rim even involves the government using giant robots called Jaguers controlled by two soldiers to fight off monsters called Kaiju, which is the exact species that Godzilla belongs too. So pitting Jaguers against THE Godzilla itself would actually make a lot more sense then a sequel of them just fitting more random Kaijus. There's also the fact that the original Godzilla franchise itself has been famous for pitting Godzilla against another threat of large scale such as King Kong Vs Godzilla, Mothra Vs Godzilla, Godzilla Vs Destoroyah, Godzilla Vs Mechagodzilla, and more.
So what do you think of a Pacific Rim/Godzilla crossover? What about a G.I. Joe/Transformers one?
