This transfers the conventions of the sport film to a circus. Burt Lancaster plays an embittered, alcoholic former trapeze flyer who was grounded after an accident attempting the ultimate, the triple somersault. Tony Curtis is the young gun who arrives in Paris to learn the triple off the master, and perhaps save him from self destruction.
They are joined by another archetype. Gina Lollobrigida is a hot tempered Italian acrobat who wants to break into their team. She gets between the two men and threatens the purity their act with her showbiz glamour. They become a threesome in the air and on the ground. The implication of homosexuality between the men is subdued, but still present.
It's the best circus film there is. While it is full of genre clichés (we don't get a sad clown) these are made fun by great star performances, and spectacular action photography, in Technicolor. Carol Reed captures the flaking exoticism of the ring and the seediness of their assignations in trashy Parisian hotels. It's a sexy melodrama.
Gina is fabulous in her sequinned leotards. The sassy dialogue uses the ecstasy of the high wire act as ominous innuendo for sex, which makes the film feel quite noirish. Maybe not one of (former trapeze artist) Burt Lancaster's more prestigious roles, but it's entertaining and a reminder of his imposing physicality and athleticism.
