One season, two flags
A show's casting call usually stays inside its own borders by default, not by rule. These are the seasons that broke that default on purpose — one national divide or one borrowed roster, structural for exactly one run and never repeated the same way twice.

The 9, in order.
- #01
A tenth-anniversary format that shrinks the whole season around the international divide.
Ten episodes instead of the usual near-two-dozen, half the standard cast, and a straight split — seven Australians against seven returning international franchise veterans. The compressed format only exists because of the crossover premise. - #02
A fresh-blood sequel gets a second structural layer: an explicit US-versus-UK rivalry running under it.
The returning-rookies format from the first War of the Worlds gets a rivalry spine bolted on, with the incoming cast split cleanly by nationality. Filmed across Chiang Mai and Phuket, the alliance math runs along that line all season. - #03
Nine Britons against nine Americans, with the production itself split across two countries.
Cycle 18 doesn't just cast internationally — it structures the whole competition as a transatlantic contest, shooting legs in both London and Hawaii. The nationality line is the season's actual format, not a casting footnote. - #04
A World Cup structure divides the flagship's cast into four regional teams instead of one open field.
Twenty home cooks split into four groups by global region — Europe, Asia-Pacific, Africa, and the Americas — for a World Cup-style bracket, filmed in Toronto. The flagship's most explicitly international structure yet, down to a hiatus timed around the real tournament. - #05
A kitchen built entirely from alumni of Top Chef's international franchises, not its home roster.
Every competing chef learned the format under a different flag — the cast is imported wholesale from sibling editions around the world, cooking in London with a Paris finale. Padma Lakshmi closes out her hosting run on the swap. - #06
The format's first trip outside the US comes with a roommate list built to cross borders on purpose.
Three Americans, two Britons, a German, and an Australian share a Notting Hill flat — the franchise's first deliberately international cast, and its first season filmed entirely abroad. The mix aims for a lighter, funnier register than the two seasons before it. - #07
An American Dream theme staffed by a genuinely international brigade, not just American hopefuls.
Eighteen chefs from well outside the usual domestic pool cook under a theme explicitly about American opportunity, in the show's last California-based season. The contrast between the theme and the cast's range does real editorial work. - #08
The crossover pool finally reaches past America's own dating shows into an international one.
Three seasons of pulling alumni from Love Is Blind and Too Hot to Handle give way to a fourth that also recruits from Married at First Sight Australia and Vanderpump Rules. Eight episodes, the shortest run yet, hold the villa's biggest cast. - #09
A Winter-Games-style crossover folds in whole delegations from three sibling international editions at once.
Contestants from Bachelorette Canada, Bachelor New Zealand, and Bachelor Japan join the domestic cast in a Winter-Games-style crossover, an import the spinoff never repeated. Nineteen arrive day one, with sixteen more staggering in later.
