10 Major Details Marvel Just Revealed About Thor: Ragnarok

2. Jaime Alexander Won't Be Back (But Sif Could Still)

In more cast change news, it's been revealed that Jaime Alexander is unable to return for Ragnarok thanks to a scheduling conflict with new critically acclaimed show Blindspot. That's despite how confident she was that Lady Sif would be getting an expanded role for the sequel earlier in the production process.

There's also no mention of Thor's other warrior allies, Volstagg, Fandral and Hogun. With Asgard torn apart by all-out war, it's unlikely the most famed warriors on the planet are going to sit it out.

And frankly, with Jane Foster and her gaggle of comic relief sidekicks gone, Taika Waititi is going to need an opportunity to add some laughs, and the Warriors Three have played that role somewhat in the past.
