It's been 40 years since Sylvester Stallone first climbed into the ring and onto the silver screen as Rocky Balboa, the down-on-his-luck boxer with a lot of heart.
Since the iconic rag-to-riches story was released on Nov. 21, 1976, it has spawned six sequels (some great, some...well, not so great) and countless posed photos at the top of Rocky Steps, the 72 steps that Stallone famously sprinted up during his training.
On this 40th anniversary, we give you 10 facts about the original "Rocky" that started the phenomenon.
1. Stallone's film was shot in 28 days on a budget just over $1 million. Producers fought with Stallone over shooting exteriors in Philly; they wanted to keep costs low and shoot entirely in Los Angeles, because they had personally guaranteed to cover any costs over the $1 million budget.
2. Shooting in Philly was on a tight budget. No artificial lighting was used for exterior shots, and actors had no trailers or catering. Only one on-set meal was served for breakfast, lunch and dinner: pizza.
3. Rocky's real name is actually Robert, but the nickname is used to honor real-life boxer Rocky Marciano.
4. Stallone downed raw eggs before his training montage. According to the actor, that was an easy feat. He'd done it plenty of times when he was living in a New York City apartment with no stove.
