The Avengers: Age of Ultron may bring together Earth's Mightiest heroes. Batman v Superman: Dawn of Justice may be set to unite the Justice League on the big screen for the first time. There is one thing, however, that neither film will ever be able to do: unite the Marvel and DC universes.
One film, though, might just be able to.
Now, normally this would all be a matter for fan conjecture and comic crossovers, and nothing more. Thankfully, though, we live in a brave new world. A world which features Phil Lord and Chris Miller, directors of The Lego Movie. A world, in short, full of infinite possibilities - and in this world, anything could happen.
Even seeing DC and Marvel face off on the big screen.
Lord and Miller recently discussed with Coming Soon whether or not we could - just maybe - expect to see both Marvel and DC heroes appearing in the upcoming sequel to The Lego Movie.
Their response? Not as negative as you might think.
Though Miller admitted that Marvel “don’t need LEGO to make their movies successful," he and Lord seem cautiously optimistic that a deal to bring The Avengers to The Lego Movie 2 could yet happen. As Lord puts it: "Hopefully it will be like another '[Who Framed] Roger Rabbit' situation where, ‘Of course, we’d love to be a part of this,’ but who knows?”
Superman and Green Lantern bickering like schoolkids could seem like a whole lot of nothing special if we get to see The Hulk go toe to toe with Supes in the sequel - or see who can win in an optimism-off between Captain America and The Lego Movie's Emmet.
If, as Lord and Miller suggest, such an epic crossover is indeed possible - it also opens up the doors to some equally incredible appearances from LEGO-adapted stars. Is there any cameo - or major role - we could be set to see in The Lego Movie 2 that could compete with Marvel v DC for sheer spectacle?
Let's take a look at some of the contenders that we'd love to see come the sequel's release (Note, if you haven't seen The Lego Movie yet, thar be SPOILERS below - also, what's taken you so long? It's fantastic...):
LEGO Star Wars
The good folks over at Film Divider have taken a look at the original draft of The Lego Movie's script - and it's fair to say that it changed a lot before reaching the screen. One of the biggest alterations? Chewbacca and R2-D2 would have been substantially featured - with Artoo a fully-fledged member of Emmet's gang. Could the sequel give us a better look at the Star Wars LEGO universe? With the first two films of J.J. Abrams' new trilogy set for release either side of The Lego Movie 2, it could be a cross-promotional match made in heaven. Uni-Kitty on Endor, anyone?
LEGO Harry Potter
We may have had a great Dumbledore/Gandalf gag in the finished film - but that same first draft of The Lego Movie included Harry Potter turning up in the final battle - a feature that is practically begging to be included in the sequel. Throw in Hermione, Ron and a Hogwarts setting, and you have a serious LEGO stew going. With the impending Duplo threat on the horizon, a little magic might just be sorely needed.
LEGO Indiana Jones
While most of the LEGO franchises got at least some sort of recognition in the final film, Indiana Jones was left out in the cold. The original draft of the script may have featured an excellent gag with Indy and Han Solo recognizing one another - but it didn't make the final cut, whether for licensing or creative reasons. Could this leave space for Indy to be the sequel's break out star, in the vein of Batman's egotistical third of the central love triangle? Just think of the fun they could have with some recurring LEGO snakes...
LEGO Pirates of the Caribbean
While not exactly the most popular LEGO sets out there, Cap'n Jack Sparrow and pals are still very much part of the extended LEGO universe - with numerous sets and a video game - and there are few more iconic figures out there than Depp's Sparrow. Could a similarly timed release for the next Pirates installment encourage a suitable Depp-filled cameo in The Lego Movie 2? Also, pirate-themed LEGO! Just think of the LEGO-monkey cameo possibilities...
LEGO Lord of the Rings
Another franchise that was originally an integral part of the film - with hobbits cropping up all over the place - the Lord of the Rings universe's role was ultimately whittled down to a minor gag or two. Surely the potential for LEGO Gollum-themed antics would melt the cold hearts of the sternest of contractual lawyers when it came to the sequel, though? Smeagol wouldn't hurt a fly, silly hobbitses...
[The LEGO Movie 2](movie:1231804) is currently set for release on May 26, 2017
