Hollywood star Brad Pitt and his wife Angelina Jolie were missing at George Clooney and Amal Alamuddin's nuptials, but the "Ocean's Eleven" star says he was caught up with shooting.

Clooney wed British human rights lawyer Alamuddin in Italy Sep 27 with many of the actor's famous friends in attendance.

When asked about his absence from his friend's special day, Pitt said: `We were filming in Malta`, referring to his new romantic film with Jolie, `By The Sea`.

Pitt, who spoke on the sidelines of the red carpet premiere of his new film "Fury", is also yet to gift Clooney and Alamuddin a wedding present.

`I still owe him something,` he said.

Meanwhile, he's awaiting the release of "Fury`, which also stars Shia LaBeouf, Logan Lerman, Scott Eastwood, Jon Bernthal and Michael Pena.
