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 7, in order.
- #01A 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.
- #02A 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.
- #03Nine 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.
- #04A 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.
- #05The 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.
- #06An 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.
- #07The 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.
