George Clooney has been sidelined from the Venice Film Festival due to illness.

The Oscar-winning actor, 64, was absent from the Venice press conference for his movie "Jay Kelly" on Thursday, Aug. 28.

"George has been diagnosed with a sinus infection and is under doctors orders to cut back all activities today," Simon Halls, a representative for the actor, confirmed to USA TODAY.

The press conference went forward without Clooney, with director Noah Baumbach and stars Adam Sandler, Laura Dern, Billy Crudup and Emily Mortimer speaking to reporters.

"Even movie stars get sick," Baumbach quipped.
