Angelina Jolie

When she signed on to star in Lara Croft: Tomb Raider, Angelina Jolie was an avid smoker.

However, the actress dropped the habit to ensure she was up to the physical challenges of the 2001 action flick.

She said: "I admittedly came [in] smoking two packs a day and completely had to change my health and my life and discover that I could do things I didn’t know I could do."
