The period drama detailing events in the reign of Queen Elizabeth II will begin filming on location in parts of Andalusia during October.
The first casting call for extras took place in the town of San Juan de Aznalfarach on Thursday when more than 500 people turned up for the chance to be cast in crowd scenes that will be filmed in the town during the Autumn.

A further casting is taking place Friday in Jerez and two more will be held next week for filming that is planned between October 8th and 24th.
Casting sessions will occur in Algecerias on August 20th and in Fuengirola (Malaga) on August 22nd.
The profile for all the extras is the same. Producers are looking for men and women aged between 25 and 65 or 70, either Latino or Anglo-Saxon appearance, and without visible tattoos or highlights in their hair.
The third series of the hugely popular drama will chart the life of the Monarch and her family from 1964 onwards and will see a new cast in the leading roles.
Olivia Colman will take over from Claire Foy as Her Majesty while Tobias Menzies is taking over from Matt Smith as Prince Philip and Helena Bonham Carter is replacing Vanessa Kirby as Princess Margaret.
It is thought that various sites in Andalusia have been chosen because of their 1960s architecture which can be transformed to resemble key locations visited by the Monarch during that decade.
For example, a conference centre in Torremolinos which maintains its 1960s look, has been picked for an airport scene in the Netflix series, according to local newspaper, Diario Sur.
