I first became a fan of Robin when he played Mork, the alien on Mork & Mindy.
I was a kid back then. If you had asked me who my favorite comedian was, back then, it would have been either Mork, or Jack Tripper (John Ritter) on Three's Company. Later I saw Robin play great roles in movies like Good Morning Vietnam and Good Will Hunting. He was a genius. Never knew he was a tortured soul too. Wish I knew more about his life. I'm sure there are lessons in it...
I didn't know Lauren Bacall's work quite as well, but I was impressed with her role in Casablanca. I'm sure I saw her in some of the great supporting roles she had later in her career, but the names of those films seem to escape me right now. What sticks with me is that she always appeared as a Lady.
