Summer Movie Spin-Offs of Our Dreams

In 1955, Biff Tannen got punched out by a vengeful George McFly. Thirty years later, Biff was a quavering shell of his former self. And by 2015, he was an embittered geezer, encompassed by a life of regret. So where's his story? What happened to Biff in the '60s and '70s? Why couldn't he turn his life around? Well, that's exactly what 'Back to the Future Part IV: The Ballad of Biff' would explore. [Universal Pictures]

For some odd reason, the 'Iron Man' movies have lent particular focus to the bionic superhero/multi-billionaire/egomaniacal titular hero, when the real star of the show should be his no-nonsense right-hand man Happy Hogan. Perhaps in a fourth feature for the Marvel character, former director Jon Favreau's Happy Hogan can take charge, saving the world from any number of supervillains while Robert Downey, Jr.'s character takes an island vacation with Pepper Potts.

While Harry Potter's travails might have come to an end, there are still worlds to be explored in the Hogwarts realm. For instance, what exactly goes on at the Weasleys' Wizard Wheezes joke shop all day? What sort of comical misadventures to twin brothers Fred and George Weasley get themselves into while peddling Extendable Ears and Pygmy Puffs. Not quite as exciting as the other stories, maybe, but 'Harry Potter and the Weasleys' Wizard Wheezes' could well be the funniest flick in the series. [Warner Bros.]

Before Aasif Mandvi was a recognizable 'Daily Show' correspondent, he was the pizza parlor boss of delivery boy Peter Parker, a.k.a Spider-Man. And while Spider-Man might be able wage war on crime, what about the economy? It's workers like him — careless, selfish numbskulls — who are the enemy to a thriving financial structure. But hard-nosed, diligent workers like Mr. Aziz are the heroes in this story: 'Spider-Man 4', a tale about one business owner's plight to turn things around for the American working man.

In 'Men in Black 3', the world found out an interesting bit of information about the artist Andy Warhol: he was an agent. We only got to see a quick glimpse into the secret life of the man who made a can of tomato soup into an icon of American art, but there's more to the story! What was the truth behind Warhol's wacky persona? Was it part of a complex effort to track down aliens, or just a fun cover for his hidden identity? 'Men in Black 4: This Means Warhol' should really look into this plot. [Columbia Pictures]

Ridley Scott's highly anticipated 'Prometheus' might have fallen short of delivering a worthy introduction to the universe of 'Alien', but there was one thing it gave audiences that was undeniably brilliant: Idris Elba playing the ukulele. This scene deserves a movie all its own. Elba traveling the galaxy, playing the ukulele to coerce women like Charlize Theron into casual love affairs. It's fun for the whole family! [20th Century Fox]

We've gotten a good look at many of the citizens of Gotham. But there is one character — group of characters, rather — who haven't gotten much more than a few glances: Bruce Wayne's assortment of lady friends. Sure, he had a special place in his heart for Rachel Dawes, but through 'Batman Begins' and 'The Dark Knight', Wayne was seen with a good amount of ladder-climbing young women. So where were they once he disappeared into the dark to save the city? And how did not ONE of them ever even get an inkling of who they were dealing with? 'The Dark Knight Cruises' will step away from Batman, and take a look at his casual companions. [Warner Bros.]

The 1975 classic 'Jaws' spawned three sequels, all oddly focal on the Brody family. But there is one man, introduced in the original movie, who needs his day in the sun: Harry. You know, Harry. The guy with the bad hat. Remember? "That's some bad hat, Harry"? What if the brethren of the monster shark returns to the beach years later, and the only man who knows how to deal with him is the unorthodox habidasher: beach bum Harry. That hat can handle anything. [Universal Pictures]

The 'Star Wars' universe is filled with droids, spanning five classes and countless varieties (protocol, astromech, the lizardy ones). But for some reason R2-D2 and C-3PO hog most of the mechanical spotlight, much to the chagrin of one particular member of their robotic brethren: R5-D4, the infrequently referenced droid that broke down just in time to convince Uncle Owen to purchase R2 instead. So what, did R5 just get sold for parts by those sheisty jawas? Or did he roam the galaxy, searching for meaning, influencing people and Wookkies alike, and perhaps contributing to the downfall of the Empire? Only 'Star Wars Episode IV 1/2: This IS the Droid You're Looking For' can tell. [20th Century Fox]
