Mark Kerr, known variably as "The Smashing Machine" and "The Specimen," is a very definite contradiction in terms. On one hand, as the one-time "baddest man on the planet," Mark looked like comic icon Hellboy, come to life. And he lived that life in a self-imposed hell of his own making, which was painfully chronicled in the cautionary, eponymous documentary, "The Smashing Machine." On the other hand, Mark is an incredibly cultured, deeply introspective and highly intelligent individual, which has made him more sensitive than most to life's highs and lows. On Talking Tough, Mark and Rick talk openly about: Drug use, and abuse Irresponsibility, and accountability Tall tales from the days of UFC and PRIDE Successful fatherhood The "comeback" each has made in his life, which includes Mark partnering with Dwayne "The Rock" Johnson, who will portray Mark in an upcoming, major motion picture Ultimately, owning up to being a man, and a responsible citizen Rick and Mark have a long-lasting and deep connection, which is reflected in this exceptionally candid conversation.
