For decades now, Robert Cavanah has been a British actor with a career measured in decades rather than seasons. The first credits arrived long before the title most people know. Work has kept arriving for 32 years, which is its own kind of achievement. If one title has to stand in for the rest, it is 'Lara Croft: Tomb Raider - The Cradle of Life'. There is 'Sahara' as well.
