Straight man
IMO, Gabor's comment essentially means don't step on my punch line ... that makes more sense given the time period and context.
As for the film overall, watching on TCM in September 2025, it plays better than it seems to have done originally. Probably because it's enough to a time capsule now to enjoy the look and Sixties Euro feel over any staleness with the cat burglar plot.
George Harrison, the actor, is fun to see given the fixation later on his tan. I believe he was 28 when this film was new and enjoyable to see as a young man.

" You may rely on Helmut "
"The Jack of Diamonds" is a most enjoyable film, for fans of Mr. Hamilton. The story is that of a retired jewel thief (Joseph Cotton) who is known as "The Ace of Diamonds." Although he has long since retired, his new protégé George Hamilton has earned the reputation of a world class Cat Bugler and is so proficient he has come to the attention of international Insurance investigator Von Schenk (Wolfgang Presiss.) The insurance organization and the police are very interested in capturing him and the other two re-known jewel thieves like the King and Queen of Diamonds, (Murice Evans and Maire Laforte) and their aid Helmut (Karl Lieffen). They plan on going after the World Series of Jewels called the Hazerhoff Collection and will need all their collective skills to obtain it as it is not only well guarded, but the insurance company is waiting for them to try. Fun is an understatement, as the combined star power makes the film as interesting as the caper itself. A good film in any sense of the word. ****
"This is a robbery, not an adventure!"
Modern-day Canadian cat burglar, young, handsome and rich, steals precious gems from wealthy women all over the world; he's mentored by a veteran thief, both of whom become begrudging partners with a female cat burglar and her stepfather, who has concocted his own Mission: Impossible--stealing royal blood red diamonds from an impenetrable vault. Disposable caper, written by four screenwriters (Jack DeWitt, co-producer Sandy Howard, Howard Joseph and Robert L. Joseph), has tongue in cheek and brain in neutral. The tinkling background score from Peter Thomas and Bob Harris lends the proceedings some groovy charm, but lead George Hamilton (while agile) fails to lighten the load with his nondescript personality. Star cameos by robbery victims Lilli Palmer, Carroll Baker and Zsa Zsa Gabor (playing themselves) are incidental, though Gabor makes the most of her screen time with a cheeky turn. ** from ****
American Take on European Jewel Thief Genre
This mildly entertaining German-American production has a Yankee take on the European tradition of suave jewel thieves. Perhaps influenced by the popular Italian comic books, star George Hamilton looks like Diabolik at times (though this movie was released before the film Danger: Diabolik).
Amusing cameos and supporting parts by many familiar faces and ably directed by veteran director/actor Don Taylor. Lots of nice Bavarian locations. Wolfgang Preiss, who played super-criminal Dr. Mabuse in a series of films, represents the law here. Even with some Morricone-ish music, one wishes it was more representative of the wild 60s Euro costumed criminal films like Danger: Diabolik, Kriminal and Mister X. The scene where Hamilton works on a trapeze in his mansion may have inspired the similar Lara Croft bit.

JACK OF DIAMONDS (Don Taylor, 1967) **
Typically glossy and bland 1960s international caper which, though harmless enough while it’s on, emerges an unnecessarily long haul because the running-time is padded with scenes in which the likes of Zsa Gabor, Carroll Baker and Lilli Palmer appear as themselves(!), purporting to be famous victims of the titular cat-burglar! The lead is played by a properly dashing George Hamilton; his mentor – the “Ace Of Diamonds” – is a suave Joseph Cotten; on their trail is insurance investigator Wolfgang Preiss – while Maurice Evans and Marie Laforet first prove rivals, then associates, in their schemes (Cotten having been involved, both romantically and ‘professionally’, with the girl’s deceased mother). Though wholly unsurprising (with the various robberies mildly generating the expected suspense), actor-turned-director Taylor’s treatment at least maintains an agreeably light touch throughout – the denouement, then, provides a clever ruse by which our roguish heroes can still go free in the end.

- TriviaGeorge Hamilton was able to demand and receive $100,000.00 for this film. He was at this time considered a hot commodity due in part to the fact that he was dating the president's daughter.
- GoofsAt the end of the first caper, Helmut is waiting for Hill in the apartment's underground garage and helps him into a Cadillac limousine. But the limousine in which they emerge onto the dark street in the next shot is a Lincoln Continental.
