George Clooney arrived in Toronto via private jet yesterday, hopping from one film festival right to the next. He had his girl Elisabetta by his side at the Venice Film Festival premiere of The Men Who Stare at Goats, but he arrived solo in Canada. While in Europe he also kept crowds entertained with his antics, jokes, and even his singing voice. Now George is at TIFF to show off his other movie getting good press, Up in the Air — check out a new teaser trailer here. Back in Italy he's still playing gracious host by opening up his Lake Como home to Julia Roberts and her family while he's away.
