>165 You're planning that out like he's a normal person, not a famous actor with an assistant, travelling first class. The assistant can get his cases to the airport, he can hop on the tube to Paddington and get the Heathrow Express (which would take less than an hour from Covent Garden), meet the assistant to pick up his cases, he then gets whisked through check-in and security and heads straight to the First Class lounge. He probably only needs to allow an hour/hour and a half at the airport because he's not going to be queueing.

So he heads to the Donmar for 9am, is finished at 10am, makes it to the airport for about 11am, is in the lounge by 11.30am, gets a 1pm flight, lands 3.30pm local time and could be spotted out and about in Toronto that evening.
