 By all accounts, Frank Sinatra (qv) was at his most obstreperous  throughout the making of this film. Among other things, he refused  to use the car supplied him by the studio, insisting upon having his  Ford Thunderbird flown all the way to Spain at the studios expense.  In addition, he almost caused an international incident when he hung  a banner from his hotel room window reading "Franco is a Fink",  referring to Spains dictator, Francisco Franco (I) (qv). In  hindsight, Sinatra referred to the whole experience as  "underwhelming".
