I want to know the answer to the following question:
Name a popular series of boxing films?
All the background I'm provided with is that "In the wildly popular Rocky series of films about the fictional boxer Rocky Balboa, Rocky III saw its hero fighting a "boxer vs. wrestler" exhibition match against the enormous and villainous wrestler "Thunderlips", portrayed by real-life soon-to-be wrestling icon Hulk Hogan.". Is that enough to answer the question?
