The director of the first Thor film, Oscar-winner Kenneth Branagh, initially had reservations about naming Thor's hammer Mjolnir due to its difficulty in pronunciation. Writer Zack Stentz revealed that Branagh had proposed the alternative name "Uru," inspired by the material from which the hammer is constructed.
At this meeting, Marvel Studios head Kevin Feige insisted on using the name "Mjolnir" to avoid disappointing passionate fans, according to reports.
"'Ken, the fanboys would have a field day with you.' 'Okay. Let's not go down that route, then,'" Stentz recounted the conversation between Feige and Branagh.
They decided to stick with Mjolnir, and the hammer became a crucial element throughout the Thor and Avengers film series. Although Hela destroyed Mjolnir in Thor: Ragnarok, it wasn't permanently gone, as Jane Foster takes up the weapon in Thor: Love and Thunder.
No new Thor movies have been announced, but it is anticipated that a fifth installment in the main series will be made due to its popularity. Chris Hemsworth's return, however, remains uncertain as he has expressed his desire not to overstay his welcome.
In the same Vanity Fair article, Chris Evans, the actor who portrays Captain America, disclosed the reasons behind his initial reluctance to take on the role.
