When “Forrest Gump” hit the theaters in 1994, it was a pure original: nothing quite like it had come before. Tom Hanks got the title role and basically hit it out of the park playing a man-child with an IQ of 75 who manages to be involved in every major happening in America between the 1950s and the 1980s. As directed by Robert Zemeckis, the film manages to move forward relentlessly in its narrative scope and, before it’s over, Tom Hanks has taught Elvis, made JFK laugh, been a hero in Vietnam, opened up China with his ping-pong skills, run across America and had a girlfriend die of AIDS. The bases are covered every which way but it’s Hanks’s dignified, down-to-Earth performance that sets it totally apart. It might be a comedy or a drama, I’m not really sure.
