According to the Leftovers actor, having his good friend Kimmel preside over his surprise nuptials was "the biggest blessing in the world." Theroux elaborated: "It was exactly what you would want him to do. He was extremely funny, kept things extremely light, was extremely touching."
In fact, the sometimes-emotional Kimmel — who choked up on air over the death of Cecil the Lion — even "cried a little bit" as his pals committed their lives to each other.
"He did," Theroux, 44, shared. "And then…everyone did. And it was just… it was the perfect tone for the night."
Officiating wasn't Kimmel's only role in the wedding festivities, though. Us Weekly exclusively revealed last month that the late-night host, 47, also hosted Theroux's bachelor party at his barn in West Hollywood several days before the nuptials went down.
Kimmel and his wife, Molly McNearney, are close to the A-listers, and joined them on vacation in December 2012 in Cabo San Lucas, Mexico. Kimmel, along with several other pals, accompanied the couple on their friend-filled honeymoon in Bora Bora.
Theroux and Aniston, 46, tied the knot on Aug. 5 at their Bel Air mansion before a star-studded crowd that included celebrities like Emily Blunt, John Krasinski, Lisa Kudrow, Ellen DeGeneres, Howard Stern, and Chelsea Handler. The actor said on Wednesday that marriage has changed him — for the better.
"It’s fantastic. Something really does shift…in a wonderful way," he told Robin Roberts. "And it sort of refocuses things… You relax into it in a certain way. I can't explain it."
He added that marriage has allowed him and Aniston to be in "the right sort of space… it's a wonderful thing, you know?"
