Thor Ragnarok is currently filming in Australia and director Taika Waititi has shared some interesting script details, teasing a scene between Thor and Hulk. The director went on to call Thor 3 as being the "most different Marvel movie to date".

In an interview with Polygon, Waititi has revealed that the movie's script is changing. "It's hard to say what the movie is because it's changing. The plot has changed and the script has changed."

"There are buddy elements to it between Thor and the Hulk, but who knows what the final movie will look like., he teased. So fans can expect some bonding scenes between Hulk – the monstrous alter ego of Bruce Banner – and Thor, which will be a treat for the Marvel fans.

The director also shared that he has the creative freedom to make script changes and as such, "I feel like a guest in Marvel's universe, but with the creative freedom to do what I want."

"If my actors aren't having a good time on set, then I'm doing something wrong. There needs to be a chemistry between characters on screen, and that comes from having chemistry on set. We're making movies. We should be having a lot of fun." he added.
