2. 'Rocky' (1976)
I can't count the number of times I've watched this movie. Who else had a Rocky t-shirt in the '70s? From having his boxing gear moved to "skid row" to calling out for Adrian (Talia Shire) after the fight, Rocky is the quintessential story of an underdog who gets a chance to be the champ. It didn't happen in the first film, but as we all know, he had five more chances to come out on top.
