The actor shot to fame for his role on 'Moonlighting' in the 1980s before being catapulted to the A-list with his starring role in the iconic 1988 action film 'Die Hard'.

In his prime, Willis was one of the world's most bankable movie stars, and starred in some of the biggest films of the 1990's including the 'Die Hard' sequels, 'Pulp Fiction', 'Armageddon', and 'The Sixth Sense'.

The 67-year old star had worked over the course of his career, starring in films from respected directors such as Wes Anderson, M. Night Shyamalan, and reprised his role as John McClane in 2013's 'A Good Day To Die Hard'.

Willis briefly had a music career, with his cover of 'Under The Boardwalk' hitting number 2 in the UK and Ireland in the summer of 1987, and was an owner of the Planet Hollywood chain of restaurants alongside then-wife Demi Moore, and fellow action stars Sylvester Stallone and Arnold Schwarzenegger.
