Actor Patrick Stewart, best known as Captain Jean-Luc Picard in "Star Trek: The Next Generation," took a turn on the torch relay Monday.
Before he did, tennis stars Andy Murray and Venus Williams posed with the flame on Center Court at Wimbledon in southwest London.
Murray said his preparations for the Olympic games have left him little time to dwell on his Wimbledon defeat to Roger Federer just over two weeks ago.
"You don't look back, you try and look forward," he said. "I'm sure the atmosphere is going to be great and I'll need all the support I can get."
The flame was also scheduled to pass through the set of the long-running British soap opera "EastEnders."
The torch relay is on its final leg of a 70-day journey, touring the neighbourhoods of host city London before being taken to the Olympic Stadium for Friday's opening ceremony.
On Sunday, the torch made a spectacular visit, travelling on the London Eye over the British capital.
The torch has visited the Channel Islands, Ireland, Northern Ireland, Wales and Scotland and gone past national landmarks like Stonehenge and Mount Snowdon.
