25 Best Easter Eggs & References In The MCU So Far

20. Rhodey's Ringtone (Iron Man)

In the first Iron Man movie, when Tony Stark's best friend James "Rhodey" Rhodes has pilots chasing down a Stark-shaped "bogie" after Stark had liberated an Afghan village from their terrorist captors, he gets a phone call from Stark - who attempts to deny any knowledge of the incident - and his ringtone is a funky little midi version of the 1966 Iron Man cartoon theme music. Also, in the same movie, as Tony and Rhodey walk through the casino in Las Vegas, the music in the background is a jazz version of the theme from the same 1966 Iron Man cartoon series. Not the easiest Easter eggs to identify but, if you're remotely familiar with the relevant series, you will have recognised the tune instantly.
