Talk about a comeback -- Mickey Rourke has gone from wrestling his way back into our hearts to getting cast in what is perhaps the biggest blockbuster of 2010: Iron Man 2. Variety tells us that Rourke is in talks to play a villain that's described as "Tony Stark's Russian alter ego, a heavily tattooed bruiser who is in the arms trade and battles Iron Man in his own nuclear-powered armored suit." Though the script isn't finished yet, most likely the character will be that of Crimson Dynamo. From Wiki: "The first Crimson Dynamo was also the creator of the armor: Professor Anton Vanko. A Soviet scientist of Armenian birth with a PhD, Vanko was the world's foremost expert on electricity. He built a suit that was wired up to perform electric miracles, making him a human dynamo. The Crimson Dynamo battle-suit allowed him to control electricity in all of its forms, allowing him to fire devastating bolts of electricity. It also allowed him to fly." THR, however, mentions that Rourke is playing the villain Whiplash, who's also known as Blacklash, "a man with deadly, technologically enhanced coils." Rourke also signed on to star in Sylvestor Stallone's The Expendables, as reported earlier, which means the man is taking all he can get.

According to casting calls, they still need to cast an "Eastern European, brilliant, gritty" male lead in his thirties and a "beautiful [female lead who] speaks several languages fluently and is equally proficient in martial arts" in her twenties, who is Tony Stark's assistant Natasha (as per THR). Mickey Rourke playing villain in Iron Man 2? What do you think about all this? We'll have more as it develops -- Iron Man 2 hits theaters on May 7, 2010.

UPDATE: Sam Rockwell is also circling the role of Stark rival Justin Hammer (which takes care of our "Eastern European, brilliant, gritty" male lead").
