I'm sorry, but that seems like overkill. Getting tired is understandable, as is needing a break. But let's recap. In the last few years, there was Goya's Ghosts, No Country for Old Men, and Love in the Time of Cholera. He's topping that off with two more -- Vicky Cristina Barcelona and Killing Pablo. Needing a year break after this seems like overkill. I mean, in the same amount of time, Peter O'Toole has taken on 12 roles (being 37-years Javier's senior), Scarlett Johansson, his Vicky co-star, has nine roles, a TV gig, and a directorial gig, Robert Downey Jr. has 11, and so on and so forth.
If this handful of roles and awards has worn him down too much, I have to wonder if he will be able to continue this career for many years to come. Then again, maybe he isn't tired of working, but just tired of the big-name system. Since he got his first credit role in The Ages of Lulu in 1990, he's had at least one gig a year, except for 2005, which remained Bardem-free. It's not like he's a complete newbie. Oh well. At least we still have Vicky and Pablo on the way.
