10 Biggest Fan Service Moments In Marvel Movies

10. JARVIS - Iron Man

When looking back on the history of Iron Man, people tend to forget about how integral JARVIS was to helping Tony Stark reach his fullest potential.

After all, since our favorite artificial intelligence was folded into Vision later, how the hell were you supposed to keep up with him when you had to worry about all the other side characters coming in every new MCU movie? People were paying attention to the explosions so much that most probably didn't even realize his name was an anagram.

Yeah, for as much as the name Jarvis sounds like an upscale butler in the vein of Alfred Pennyworth, the letters act as an acronym for Just A Rather Very Intelligent System, modelled after the actual butler Tony has as a kid in the comics. Though we do get a glimpse of the real Jarvis towards the midpoint of Endgame, this is the kind of Easter Egg for the comics nerd who really know their stuff.

As opposed to your casual movie fan, the acronym would probably fly over most people's heads, thinking that it's just some hoity name to give your butler and nothing else.

While most of JARVIS' operating systems have been made into Vision nowadays, this remains one of the few Easter Eggs that doesn't deserve to go over the heads of the fairweather fans.
