Princess Leia as a D.C. madam?  The Blues Brothers as Amigos?  Who wouldn't have wanted to see that?

We delve again into the hypothetical world where actors got the roles they missed out on.  Where 'Mrs. Doubtfire' was a 'Home Improvement' adaptation, Jackie Chan ran into Big Trouble in Little China, and Sandra Bullock didn't become America's Sweetheart in 'Demolition Man'.

  • James Remar as Corporal Hicks in ‘Aliens’

    James Remar was originally cast as Corporal Hicks, but was replaced by Michael Biehn a few days into filming. The original reason given was creative differences between Remar and director James Cameron.  It wasn’t until years later when Remar set the record straight on a podcast, saying he was fired from the film after being arrested for drug possession.  Biehn was called on Friday and asked to take over the role, and had to be in London for filming on Monday.

  • David Bowie as The Joker in ‘Batman’ and Max Zorin in ‘A View to a Kill’

    Legendary musician David Bowie nearly added Batman’s greatest foe and a Bond villain to his resume. One of several actors considered for the Joker in Tim Burton’s ‘Batman’, Bowie was a favorite among fans and even comic book artists who continued to model the Joker after Bowie even though he didn’t get the part.  Bowie was also approached for the lead villain role, Max Zorin, in the James Bond film ‘A View to a Kill’.  However, Bowie turned down the role after reading the script, citing a lack of enthusiasm for the project.

  • Leonardo DiCaprio as Rick O’Connell in ‘The Mummy’

    Rumor has it that Leo DiCaprio was offered the lead role in the Universal reboot of ‘The Mummy’, but was unable to accept the part due to commitments to ‘The Beach’. DiCaprio reportedly loved the script and even tried to have production delayed on ‘The Beach’ to allow him to do both.  Ironically, after the part went to Brendan Fraiser, production on ‘The Beach’ was delayed anyway.  Other names considered for O’Connell included Sylvester Stallone, Brad Pitt, Matt Damon, Ben Affleck, Chris O’Donnell, Matthew McConaughey, and Tom Cruise, who is starring in the 2017 reboot.

  • Peter Capaldi, Christopher Eccleston, and Anthony Stewart Head as The 8th Doctor and Christopher Lloyd as The Master in ‘Doctor Who’ (1996)

    When the BBC was looking to relaunch the ‘Doctor Who’ franchise in the 90s in America with a made-for-TV movie, future Doctors Peter Capaldi and Christopher Eccleston were both asked to audition for the role. Both declined, with Capaldi believing he didn’t stand a chance and Eccleston feeling it was too early in his career to attach himself to a beloved franchise.  Anthony Stewart Head auditioned for The Doctor before becoming Buffy’s Watcher Giles in ‘Buffy the Vampire Slayer’ (Head would eventually guest star in the second series/season of the relaunched BBC series), and Christopher Lloyd was wanted for the role of The Doctor’s nemesis, The Master, but producers vetoed his consideration out of concern for how much they’d have to pay him.  Ironically, they ended up paying Eric Roberts more than they would have had to pay Lloyd.

  • Tim Allen as Daniel Hillard/Tim Taylor and Blake Lively as Natalie Hillard in ‘Mrs. Doubtfire’

    Rumors suggest that at some point during the process of adapting ‘Mrs. Doubtfire’ from book to screen, the idea was suggested of adapting it into a feature film version of ‘Home Improvement’, and changing the characters to fit those from the show. Stars Tim Allen and Patricia Richardson reportedly hated the idea and felt that ‘Home Improvement’ didn’t need a feature film.  When the film was going forward with Robin Williams, a young Blake Lively was a main contender for the role of the youngest Hillard child, Natalie.  Lively made it to the final round of auditions, losing out to Mara Wilson in her feature film debut.
