WATCH: The Rock sends video message to Irish teen battling cancer

"I've never met you, but I already know so much about you and can tell you're an awesome, honorable and strong young man."

Wrestler-turned-movie star Dwayne ‘The Rock’ Johnson has a reputation for being an all-round good guy - and he showed why when he took the time to send an important message.

Johnson was told about a 15-year-old boy from Mayo, Tommy Hanley, who is currently fighting a battle with cancer.
