21. Rhodey’s Ringtone for Tony Stark
Rhodey and Stark have a pretty strong friendship that seems to withstand the tests of time and conflict. Every time Stark gives his friend a call, you’ll hear a cute little ringtone coming out of his phone. The significance? It’s the theme song from the 1966 Iron Man cartoon show. Whoever thought to include that little jingle in the movies is either a genius or knew to do their homework. You can actually hear the theme song sprinkled around in other parts of the movie’s soundtrack.
