Festival show 'leaving planet earth'

Scottish theatre company Gridiron is renowned for making work in unusual places.

Performances have been staged beneath the Royal Mile, at Edinburgh airport and in a morgue.

The latest show for the Edinburgh International Festival will take it to new territory entirely.

"Leaving Planet Earth" uses the Edinburgh International Climbing Centre and is already sold-out.

BBC Scotland's arts correspondent Pauline McLean reports on what looks like one of the hits of the Edinburgh International Festival.
