Joss Whedon And Tom Hiddleston's 'Avengers' E-Mails Reveal A Beautiful Bromance

Earth's mightiest pen pals!

"Thank you for writing me my Hans Gruber. But a Hans Gruber with super-magic powers."

That's just one of the choice effusions of praise contained in Tom Hiddleston's e-mail to Joss Whedon, penned and sent shortly after his first time reading the script for "Marvel's The Avengers." Hiddleston's correspondence with Whedon (and Whedon's subsequent reply) is captured in the pages of "Joss Whedon: The Biography," penned by Amy Pascale and hitting shelves via Chicago Review Press on August 1.

In the e-mail, Hiddleston offers up his immense gratitude for Whedon bringing so much depth to the character of Loki, the Asgardian mischief-maker first seen in Kenneth Branagh's "Thor," and the villain responsible for bringing Earth's mightiest heroes together. Hiddleston compares Whedon's vision of Loki to Alan Rickman's aforementioned "Die Hard" villain, one of the great bad guy roles in action movie history.

"It's high operatic villainy alongside detached throwaway tongue-in-cheek; plus the 'real menace' and his closely guarded suitcase of pain," Hiddleston wrote in his e-mail, obtained by The Wrap. "It's grand and epic and majestic and poetic and lyrical and wicked and rich and badass and might possibly be the most gloriously fun part I've ever stared down the barrel of playing. It is just so juicy."

For his part, Whedon replied to Hiddleston's epically written (and epically long) e-mail with a much shorter, but no less heartfelt sentiment:

"Tom, this is one of those emails you keep forever. Thanks so much. It's more articulate (and possibly longer) than the script. I couldn't be more pleased at your reaction, but I'll also tell you I'm still working on it … Thank you again. I'm so glad you're pleased. Absurd fun to ensue."

We might not see Hiddleston's Loki in Whedon's hands ever again, but even if we don't, we'll always have "Marvel's The Avengers," and this e-mail exchange, to treasure forever.
