From 'Deadpool' To 'Green Lantern,' From 'Harry Potter' To 'Twilight': Franchise Double Dips

Ryan ReynoldsHistory was made on Friday when Ryan Reynolds officially became the first actor to star as both a Marvel and DC Comics character. Fresh off of his spin-off spinning turn as Deadpool in "X-Men Origins: Wolverine," Reynolds is now getting to headline a “Green Lantern” film.

The "Van Wilder" star is just one of many actors who have made the smart –- and profitable –- choice to double-dip in the biggest and the best film franchises. Here is a look at a few of Hollywood's other famous double-dippers.

Harrison FordHarrison Ford: Arguably the most iconic double-dipper, Harrison Ford managed to star as two of the biggest nerd-culture icons ever within a four year period. The debate over who is cooler, Han Solo or Indiana Jones, still rages on (my ball’s in Han’s court -– he has the Millennium Falcon and a Wookiee best friend!) across the Internet. One thing is for sure though; Ford set the bar for his career early on by making the smart decision to play both Han and Indy.

Ian McKellenIan McKellen: One is good, the other is evil; one destroyed the Nazgul, the other controls metal; one has a beard, the other doesn’t. What Gandalf and Magneto do have in common is the man who played them: Sir Ian McKellen. Similar to the Ryan Reynolds films' conflicting release dates -- both are set to hit theaters in 2011 -- McKellen had the fun job of promoting both “The Lord of the Rings: Return of the King” and “X2” in the same year. “Rings” beat out “X2” in the box office (and at the Academy Awards), but only in cross-over heaven will we know if Gandalf could defeat Magneto as soundly.

Christopher LeeChristopher Lee: The same year he turned 80 years old, Christopher Lee was not only reprising his role as Saruman in “The Lord of the Rings: The Two Towers” but also joining the long line of “Star Wars” baddies as Count Dooku in “Star Wars: Episode II - Attack of the Clones.” Lee’s fantastic performances as both franchises' secondary antagonist proved why he has been a heavy hitter in Hollywood since the late 1940s.

Christian BaleChristian Bale: We all know the anger that rests in the dark heart of Christian Bale, and it has nothing to do with his on-set tirades. First Bale helped reboot "Batman" as a viable mature-themed film franchise in "Batman Begins" and "The Dark Knight." Then he stepped into the giant shoes of humanity's savior, John Connor, in this summer's "Terminator Salvation." Man vs. machine or man vs. costumed criminals... doesn't matter, so long as that man is Christian Bale.

Robert PattinsonRobert Pattinson: Before you scream “OME!” take a second to remember RPattz first starred as Cedric Diggory in “Harry Potter and the Goblet of Fire,” only a month after Stephenie Meyer's “Twilight” first hit bookshelves. Cedric was a secondary character who was only around for the one film, but Robert Pattinson is the only actor who can say he’s played a character from the oft-compared "Harry Potter" and "Twilight" universes.
