Rose McGowan and director Robert Rodriguez always had a stormy relationship. It began on the set of the movie “Planet Terror,” while Rodriguez was still married but also committed to producer Elizabeth Avellán.
His marriage hit the rocks as his affair with the actress began. Their relationship was turbulent, and they struggled to stay together – fortunately, the couple called it quits.
Star Wars
Being cast as Han Solo in "Star Wars" changed Harrison Ford’s life forever. While filming, he and Carrie Fisher began an affair. Though rumors of the actors' off-screen chemistry had been the talk of the town for years, it was only confirmed years later in Fisher's book, "The Princess Diarist."
Harrison would never admit that his infidelity would be what need his marriage to Mary Marquardt.
Phantasmagoria: The Visions of Lewis Carroll
Marilyn Manson and Evan Rachel Wood’s relationship is by far the weirdest celebrity relationship of all time. The couple met on the set of Manson's horror film, "Phantasmagoria: The Visions of Lewis Carrol." At the time, Manson was married Dita Von Teese, who filed for divorce following his betrayal.
Manson and Wood had a tumultuous relationship, got engaged, and then called it quits for the last time in 2011. Years later, Manson described his involvement as a mistake, explaining, “I don't trust girls who have three names."
The Godfather
While on the set of "The Godfather," Al Pacino and Diane Keaton fell madly in love. The couple was romantically involved in an on-again, off-again relationship during the ’70s and ’80s. Keaton wanted to settle down with the actor, but he wasn't ready yet.
They continued to find a way to work side-by-side though their relationship wasn't picture-perfect, which was a true testament to their professionalism and dedication as actors. After filming "The Godfather Part III," they parted ways for the last time.
He's Just Not That Into You
Drew Barrymore and Justin Long first met when working on the set of "He’s Just Not That Into You." The two hit it off and dated during the filming, but couldn't seem to manage their off-screen relationship and broke up shortly after.
That's when fate (or Hollywood) brought them together again on the set of "Going the Distance," in 2009. The couple didn't last for long, and they broke up within months. When it's not meant to be, it's just not intended to be, huh?
