Superheroes, dinosaurs, time travel and angst-filled teenagers wanting to dance aren't exactly new ideas to Hollywood. In fact, popular ideas are milked for all they're worth.

The movie industry is always finding ways to add sequels to some of the most successful franchises. And when all sequel options are exhausted, Hollywood takes to reboots to renew interest in audiences.

It's been 10 years since the dinosaurs of "Jurassic Park" roamed the big screen, but Steven Spielberg recently revealed the movie series is far from being finished.

"We have a writer who is writing a treatment and hopefully we will make 'Jurassic Park 4' in the next two to three years," Spielberg said at Comic-Con.

Spielberg didn't give any plot details during the announcement, but Joe Johnston, who worked on the first three films, said the newest installment may be the start of a new trilogy.

The men in black will be back after a decade-long hiatus as well. The last "Men in Black" was released in 2002, and the third installment will transport Agents J and K back to the 1960s.

The plot details are being kept under wraps, but Will Smith and Tommy Lee Jones are still in the picture. However, Josh Brolin will play a younger Agent K in the time-traveling plot, according to The Daily Mail. The film is slated to hit theaters May 25, 2012.

The Bourne franchise is working on a fourth film called "The Bourne Legacy," the same title of the fourth book in the Bourne book series. But the film won't follow the book, nor will Jason Bourne (or Matt Damon for that matter) make an appearance.

"It's a completely original screenplay," director and screenwriter Troy Gilroy said on "This is not a reboot or a recast or a prequel. No one's replacing Matt Damon. There will be a whole new hero, a whole new chapter … this is a stand-alone project."

"The Bourne Legacy" will be released Aug. 8, 2012, exactly five years after the release of "The Bourne Ultimatum."

Adding to the list of action-packed franchises giving fans another film to mull over is the "Mission Impossible" series.

The first three films were spaced four to six years apart, with the first being released in 1996. But Tom Cruise will be back Dec. 21 this year as Ethan Hunt in "Mission: Impossible — Ghost Protocol," and producer J.J. Abrams gushed about Cruise still having what it takes to do the dangerous stunts.

"Tom Cruise did a number of stunts on the tallest building in the world outside the building for six days in a row," Abrams said in an Entertainment Tonight article. "I cannot honestly believe the insurance company let him do, but they did. The story is great. It's fun, I think it's going to be a really fun movie. I'm excited."

On top of pumping out sequels, Hollywood is recycling old ideas and renewing them for younger generations in the form of reboots and remakes, especially in the superhero realm.

Despite Tobey Maguire's success as Peter Parker in "Spider-Man" (2002), "Spider-Man 2" (2004) and "Spider-Man 3" (2007), Columbia Pictures is taking another shot at the franchise but with Andrew Garfield as the spider-bitten teen.

While the trailers released so far have given off a similar vibe to the earlier franchise, director Marc Webb has said the plot is going to focus more on the disappearance of Parker's parents.

"We're creating a world of our own devising, but we take cues from the comics. There's a lot of stuff to explore and define and that was part of the fun of creating this universe in a new and different way," he said in an article.

The first film is due to hit theaters July 21, 2012, and a sequel has already been commissioned with a release date of May 2, 2014.

Riding the same superhero bandwagon is a reboot of Superman set for release in 2013. "Man of Steel" will star British actor Henry Cavill as Clark Kent alongside Amy Adams as Lois Lane, with Christopher Nolan, the man behind the success of the latest Batman reboot, on board as a writer and producer.

"While David Goyer and myself were putting together the story for another Batman film a few years ago we got stuck," Nolan said in an Empire Magazine article. "(Goyer) said, 'By the way, I think I know how you approach Superman,' and he told me his take on it. It was the first time I had been able to conceive of how you would address Superman in a modern context."

A few '80s classics are getting a revival as well, including the iconic 1987 film "Dirty Dancing," with Kenny Ortega, who choreographed the original film, as director.

In a Variety article, Ortega said the opportunity is like "returning home," but the bar was set high by the first film and cast.

"I am looking forward to assembling a great creative team and an exciting cast to bring 'Dirty Dancing' to the screen for a new generation," he said.

The teens of Bomont will be antsy to dance again, as a modern-set remake of "Footloose" hits theaters in October.

"It's definitely a updated, cool version of the 'Footloose' everyone loves," said Kenny Wormald, who stars as Ren MacCormack, in an Entertainment Tonight article. "The story is the same, the heart of the story stays true to the original but Craig Brewer (director) sprinkled some contemporary elements on to it."

But the infatuation with the 1980s heartthrobs doesn't stop there. The wildly successful TV show "21 Jump Street" is being remade for the big screen with new faces, with the exception of a cameo by Johnny Depp.

According to ScreenRant, the film will follow the same form as the TV series and highlight youthful-looking undercover cops to get their foot in the door of youth crime.

"When I heard about it, I thought: 'Why not?' It seemed like a good idea. It had the right spirit," Depp said in an Entertainment Weekly article, adding that since his appearance is only a cameo, he's not sure what the movie will be like.

"I don't know what it is," he said. "But I imagine there is some sense of humor behind it."
