Odds and Evens (Italian: Pari e dispari also known as Trinity: Gambling for High Stakes) is an Italian action comedy film directed in 1978 by Sergio Corbucci and starring the film duo of Terence Hill and Bud Spencer.

In the film, a US Marine and his half-brother join forces against the American Mafia and its gambling operations.

He is tasked with teaming up with gambler turned trucker Charlie Firpo, who is - unknowingly - Johnny's half-brother.

This co-operation is first coming to fruition in a horse race where Johnny takes the place of the rider of the horse Lightning Rod, Sam Stallion, in order to win the race, while Charlie tricks one of the 'bookies' into taking an 11-to-1 odds bet on Lightning Rod.

After winning another betting match, Johnny is then taken to a cruise ship in international waters, the main base of operations of Paraboulis the Greek, where he is invited to a 'friendly family game' of poker with Paraboulis after making a big win at the roulette table, where he uses Charlie's teachings to win match after match, though Charlie intervenes after the ruse is exposed, initially confronting Johnny about it, before the two brothers turn on and beat up Paraboulis the Greek and his henchmen, rolling up the entire illegal gambling ring.
