The reason he didn't get the Bond role isn't his poor acting skill (come on - it's not like Pierce Brosnan was any better in that regard).

The real reason is the fact he's gay.

I honestly believe Craig fooled the Bond franchise stakeholders into believing he was straight - I mean he put a lot of effort into it - he's even married, and not to a random woman off the street he could easily pay off, but to a successful beautiful actress.

So, they aren't taking any chances now - and it's not like Cavill is even really trying hard to hide it - you can easily verify with a single google search that he's a flaming faggot.
