What’s the mileage count between Tennessee and Miami?
Aldrich Killian’s Mansion and grounds, where the real work of the Mandarin is revealed. The Vizcaya Museum and Gardens in Miami was used for exterior shots of the mansion.
Confirming Maya’s suspicions, we discover that Killian is actually working with the Mandarin. Later we find that The Mandarin is a ruse created by Killian to cover up accidents with his extremis experiments. The Villa Vecchia mansion, also in Miami, served as interiors for Killian’s lair.
