Would loved to have seen.
What's with Jude Law always turning down cool movie roles? Would have love to see him as Doctor Doom and James Bond.
Kinda, he wanted to dmore time to write the script but the studio was contractually obligates to release a film every so many years and didn’t give him the time to do it
