Mathew McConaughey had to go through a major physical transformation for this role. The actor lost about 50 pounds to play AIDS victim Ron Woodroof in “Dallas Buyers Club.”
The “Interstellar” actor had a hard time recovering after that role, saying that at times he would even lose his eyesight, or his legs would lock up after a short run around the block.
Marilyn Burns – Texas Chain Saw Massacre
Texas Chain Saw Massacre has been considered as of the most horrific films ever made, so probably wasn't a walk in the park to act in. Marilyn Burns endured a lot of trauma at the hands of the notorious director, Tobe Hooper. In one scene he even cut her finger open to evoke real pain.
According to what she told Terror Trap, the actress said was "a surrealistic and became so frightening because I had to be tied up and screaming for so long,” “Afterwards, I was just so grateful it was over. I probably was the happiest girl alive.”
Kyle Richards – Halloween
Kyle Richards' career goes further back than "The Real Housewives of Beverly Hills." At just nine years old, she starred in the horror film "Halloween." The actress had no real idea about what she is acting in at the time.
When she saw the movie for the first time, the actress expressed how it was the first time she pieced it together." The actress even said that she had to sleep with her mom until she was a teen. She must have been really terrified.
George Lazenby – On Her Majesty’s Secret Service
We've had a lot of James Bonds over the years, and not all of them have been up to the task. Take George Lazenby who let the role get a little to his head. The actor and former model started to believe that he was really James Bond and began clashing with the entire cast and crew.
"James Bond" even ended up bringing a real gun to set and would shoot empty bottles. Needless to say, that was the first and last James Bond film he was ever in.
Rip Torn – Maidstone
Rip Torn took things a little far during the filming of Maidstone. When director Norman Mailer told the actors that they need to plot an assassination attempt on the character, Rip Torn took that super seriously and ended up attacking the director with a hammer.
Mailer survived and wrestled Rip Torn to the ground and thankfully the rest of the cast intervened. Easy there, Rip.
