Producers of Marvel's Avengers: Infinity War and its untitled sequel are looking for males and females aged between 16 and 90 of all types and any ethnicity for filming in Edinburgh next month.

The casting call states that no acting experience is necessary, but that potential extras must have easy access to Edinburgh or the surrounding areas for filming.

The £400m blockbuster will feature scenes shot in Glasgow, Edinburgh and the Highlands.

Marvel will be using Wardpark Studios to film scenes for Avengers: Infinity War and its untitled sequel.

Avengers: Infinity War is due for release in 2018.
