Taika Waititi's working so quickly on the set of Thor: Ragnarok that one of the film's central characters is already done filming.

Following news that many of the set building crew had finished their work months earlier than originally thought, Mark Ruffalo (Bruce Banner/The Hulk) has announced he is already finished filming his scenes after only one month on the Gold Coast.

While some fans are concerned this means we won't be seeing as much of The Hulk as first thought, the majority of Hulk scenes can actually be made without Ruffalo needing to be there, on account of the magic of CGI.


And rumour has it the film will have a whole lot more Hulk than it will Bruce Banner, so it makes sense Ruffalo might not need to stay.

Either way, Ruffalo took to Instagram to document his last day on set and thanked his co-stars and director - Waititi - "for the love and the laughs", saying he "had such a great good fun time making this movie".

Laugh now, cry later.

Ruffalo's co-star Tessa Thompson, who plays Valkyrie in the film, also took to Instagram to farewell the actor they all refer to as "Ruffles".

She wrote: "Sensei Ruffles last day on #Thor3. Don't go. I was just learning how to make creepy face mask and a motion capture suit look cool".

Waititi's Thor: Ragnarok is set to be a fun, more humorous take on Thor which is already being called a "buddy film", in which Thor (Chris Hemsworth) and The Hulk (Mark Ruffalo) travel across the nine realms to save Asgard.

The film also stars Waititi's fellow Kiwi Karl Urban (Skurge) as well as Tom Hiddleston (Loki), Idris Elba (Heimdall), Sir Anthony Hopkins (Odin), Jeff Goldblum (Grandmaster) and Cate Blanchett (Hela).
