"Ocean's 11" buds Brad Pitt and George Clooney both got married this year, and in the Nov. issue of British GQ magazine, Pitt calls out Clooney and also gives his take on marriage.

The A-list actor finally exchanged vows with Angelina Jolie on their Chateau Miraval property in France on August 23, but despite being together since 2005 and having six kids, Pitt says the "I dos" still change things. "I wouldn't say [marriage is] just a title," the 50-year-old "Fury" star tells the men's magazine. "There’s more to it than that."

Adding of his views on happiness, "I've always believed happiness is overrated, you know? It’s those difficult times that inform the next wonderful time, and it’s a series of trade-offs, of events, of wins and losses."

Just this weekend, Clooney, 53, married lawyer Amal Alamuddin, 36, in Venice, and Pitt's quotes to GQ may explain why he wasn't spotted at his friend's nuptials.

When asked why he's described his co-star and pal as "unreachable," Pitt (who's from Missouri) says, "Well, you know, George is extremely accessible. He’s one of our best representatives. He’s funny as sh--. He’s a joy to be around. I guess maybe I’m more of a miserable bastard. [laughs]. I’m a bit of a loner you know? I’m more quiet by nature. And coming from, you know, hillbilly country, I’m probably more reserved."
