By 2005, though there were talks between Goyer and Marvel, Goyer was no longer interested, though at this point the film was still set to be distributed through Sony Pictures. Mark Protosevich, a fan of the Thor comic book, agreed to write the script in April 2006, and the project moved to Paramount Pictures, after it acquired the rights from Sony.

Waititi "wanted to make sure we weren't making a female character that was boring and pretty", and Feige said Marvel wanted to pair Thor with a love interest more his equal than Jane Foster. Co-screenwriters Craig Kyle and Christopher Yost's original draft of the film had more of a romantic relationship between Thor and Valkyrie.
