Recently watched a few Harold Robbins adaps.
The ludicrous Stiletto (1969), where Alex "Archangel from Airwolf" Cord plays a Mafia assassin playboy who shags Britt Ekland and constantly visits an "Italy", i.e. Puerto Rico with a few Fiats, an Italian flag and a sign saying "Italian poste", while chased by Patrick O'Neal and Roy Scheider. Features a character called "Hannibal Smith", not played by George Peppard, who alas, did appear in Robbins' Howard Hughes roman á clef The Carpetbaggers - "aka the one with the Money Programme theme, chandelier-dancing and a dying Alan Ladd as Nevada Smith". Smith, a half-Indian cowboy-turned-film star (and name inspiration for Indiana Jones) was played in the prequel by Steve McQueen, aged 35 playing 16, and people think he was old in the Blob...
Not as ludicrous as 1969's the Adventurers, intended to launch Yugoslavian Bekim Fehmiu as an international star, about a fictional Cinecitta-realised South American state of "Cortequay", where we see a skinny-dippying Ernest Borgnine seemingly cosplaying a Mexican Ted Bovis. Quickly transforming from a childhood romance to a spaghetti western, and we see that director Lewis Gilbert, who hated directing this film for he lost out on Oliver! seems to forget where exactly Corteguay is, and introduces us to a who's who of Europudding vets, Fernando Rey, Rossano Brazzi, Charles Aznavour, Ferdy Mayne, etc. Overlong and seemingly about five films in one, you have to marinate in its weirdness.
Mayne also is in the Harold Robbins miniseries The Pirate (1978), "my favourite", according to Mrs. Hamilton in Fawlty Towers. In Robbins' view of the Arab-Israeli conflict, Franco Nero as an Israeli sold at birth by his dad Eli Wallach to Sheikh Christopher Lee, to an Arabia where Ian McShane and Armand Assante are natives. Features Olivia Hussey as Leila the terrorist and James Franciscus as "Dick Carriage", and Hollywood doubling as Monte Carlo, Geneva, Israel, etc. Typical 70s network trash, punchily directed by Ken Annakin.
The Betsy (1978) is Robbins' view of the car industry, Featuring a confused chronology, 70-year-old Lord Olivier playing a dirty old car mogul, Loren "Number One" Hardeman from the age of forty to ninety, Robert Duvall as his grandson, Kathleen Beller as the titular Betsy, the great-granddaughter with a car named after, Tommy Lee Jones romancing Lesley Anne Down as the wife of a race-driving Lord, a John Barry soundtrack and feels like a driving instruction video padded out by soap opera.
