Liam Neeson is set to narrate a musical stage production of "The War Of The Worlds" - appearing to the audience in the form of a 3D hologram.
Neeson will voice the journalist character George Herbert, but he won't be there in person, thanks to the wonders of modern day technology.
The star says, "I'm not a computer nerd at all so I knew nothing about this technological stuff, but it did sound very interesting. We shot it over three days in April.
"It was all done on 'green screen' which I'm very used to after Star Wars and Clash of the Titans and various films like that. It wasn't terribly different from shooting a movie."
The play, which is based HG Wells' classic science fiction book, will tell the story of a martian invasion in England and will be staged next December.
