Will Smith turns 48-years-old today (25 September) and is undoubtedly one of Hollywood's biggest acting legends. So we thought what better way to celebrate his birthday, than to look back on what he does best; acting!

Having risen to fame in television series The Fresh Prince Of Bel Air, he transitioned into a bonafide movie star in action comedy Bad Boys opposite Martin Lawrence in 1995 and sci-fi blockbuster Independence Day alongside Jeff Goldblum the following year. Since then he has been nominated for countless awards including five Golden Globe accolades and two Academy Awards.
