Before I start let me say that this was a 2nd unit filming crew so no cast members were present - only extras. The shot being filmed was part of a sequence where Thor's hammer Mjolnir flies along the banks of the Thames towards Tower Bridge. A bike cam was used to film Mjolnir's point of view as it flies past pedestrians along side Browns Restaurant and the Design Centre on its way to Tower Bridge. The pedestrians react with surprise as it flies past. A separate camera was also set up outside the Design Centre. The rain had delayed filming until 2.00pm. The whole crew had been here since 6.00am to set up a shot that will only last 10 seconds on film!
