Asta appeared in the ‘Thin Man ‘ films with Robert Powell and Myrna Loy who played Mr and Mrs Charles. He was the child they never had and went everywhere with his human parents. They took him on trains, in taxis, on planes, cruise ships… even to restaurants.
In return Asta entertained and carried out important intelligence missions sussing out the bad guys. Often when Mr Charles was caught in a jam asta would know exactly what to do to get him out of it. Always on hand to chase a gangster up a tree, disarm a femme fatale with his winning smile or to distract an ex- con from carrying out yet another petty attempt at revenge.
Really though Asta was just your average adorable pooch and lived for his rewards.
