Best known as Loki from Thor and The Avengers, this Eton, Cambridge and RADA educated actor, is handsome, articulate and disarmingly humble (notable in a field of other similarly-privileged peers demonstrating far less gratitude for their careers --*cough*Benedict Cumberbatch*cough*). Being the delusional, hopeless fanboy that I am, I submit that there is evidence he is gay, although admittedly there is counter-evidence which suggests he's just really, really enthusiastic. Despite my prejudices in that regard, I believe the rumors that he sucked Kenneth Branagh's cock to get his big break are just that -- rumors. I think it was far more likely just a case of a mentor helping a mentee he believed in (and with good reason).
I find Loki to be a very sexually charged character in The Avengers (especiallly love the scene in Stuttgart where he walks down the steps in the D&G suit), but my favorite physical period for Hiddleston was the second season of Wallander. This was the time period in which he added 25 pounds to his 6'2' frame and grew his hair out to audition for the role of Thor (which ultimately lead to his casting as Loki). He also had a recurring role in BBC's Return to Cranford during this time, so fortunately, his hunky phase was well-documented. To have such a distinctly British look about him, he has an uncanny ability to morph his look to fit various roles. His voice is GORGEOUS. Pure sex. And he's reportedly (and observably) hung like a horse. What's not to like?
Posting a link to a ridiculous(ly entertaining) fangirl tumblr dedicated to Tom's crotch. In addition to the titular subject matter, there's also a good collection of photos there. Enjoy!
