Now the host of one of America’s most popular talk shows, Jimmy Fallon wasn’t always a hot shot.

Before becoming a late night talk show host, Fallon was a cast member of SNL and starred in films such as Taxi (2004) and Fever Pitch (2005).

As an aspiring actor, like all actors and performers, he had to go through the dreaded process of headshots – the selection of one picture that summarises what you're all about.

The picture, shared yesterday as part of #TBT, depicts an 18 year old Fallon back in 1992. He looks so serious – we definitely don’t see the host who can never stop laughing here!
