Paul Bettany's J.A.R.V.I.S. has become a fan-favourite part of the Marvel Cinematic Universe. That's despite the fact that Paul Bettany has previously admitted to not even realising that he was in a superhero movie when Jon Favreau asked him to record lines for the A.I. However, before Marvel decided to make Tony Stark and The Avengers' loyal butler a computer programme, they did consider keeping him human. However, the writers were too scared to move in that direction because they feared that they would unable to avoid comparisons to the relationship between Batman and his loyal butler Alfred Pennyworth. Despite this, a younger version of Edwin Jarvis has been introduced in Agent Carter. As many fans suspected, Tony would have had a relationship with the butler during his younger years, explaining why he chose to name his loyal A.I. - now The Vision - J.A.R.V.I.S. Oh, and in case you think there's a terribly clever explanation for the J.A.R.V.I.S. acronym, it in actual fact just stands for "Just A Rather Very Intelligent System". That makes sense!
