3. Jarvis' Potential Replacements - Avengers: Age Of Ultron
Age Of Ultron was so crammed with Easter Eggs - both obvious and completely obscure - that choosing only one would have been foolish. And ignoring this multi-reference Egg would have been criminal. When JARVIS levels up into Ultron, there's a shot showing Tony weighing up which AI to use to replace him in the Iron Man suit. Ultimately he chooses Friday (in reference to the AI secretary he built for himself in the comics), but the two he ignores are also references. They are called Jocasta (an in-comics robot built by Ultron as his wife) and Tadashi, which is a reference to the creator of Baymax in Big Hero 6.
