Too hot for insurance? Robert Downey Jr.
It took a superhuman effort for "Iron Man" star Robert Downey Jr. to escape the substance abuse that rendered him uninsurable in the late 1990s. A series of arrests interspersed with stints in prison and rehab cost Downey plenty, including his comeback role on TV's "Ally McBeal" and a Woody Allen movie. Downey's "Air America" co-star Mel Gibson even posted an insurance bond when no Hollywood studio would touch him. Now Downey champions the beleaguered Gibson.
