For the man taking the reins as the whip-cracking hero is actually a stuntman. Harrison, 78, is still recovering from a shoulder injury he got last month while rehearsing a fight scene for the fifth instalment of the Indy saga.

But his stand-in turned heads when hordes of excited fans mistook him for the real deal as they gathered at the film set in the centre of Glasgow. The stuntman was not the only thing doubling up. Plot details for the new movie are a closely-guarded secret but the Scottish city was doing a very good impression of 1960s New York.

Harrison may have been up in a hotel but his co-stars were working. Fleabag actress Phoebe Waller-Bridge was in Cochrane Street. And Boyd Holbrook, of Gone Girl and Narcos fame, was also spotted on set.
