Tom - who turns 40 on Friday - got his first acting break 16 years ago in Band of Brothers playing John A. Janovec, and in the years that followed he went on to star in Star Trek: Nemesis (2002) and Sweeney Todd as Matthew in 2006.
Obviously that was just the start for Tom, but how much has his showbiz career made him so far?
Tom is thought to have a net worth of $15 million (£11 million) as of last year, but estimates actually go up as high as $30 million (£23 million).
The actor - who was linked to the role of James Bond before Daniel Craig confirmed that he would be filling the Secret Service agent’s shoes once again - most recently starred in the likes of Dunkirk (which made $492.2 million at the U.S. box office), Oscar-winning The Revenant (that made $533 million at the box office) and Mad Max: Fury Road ($378.9 million).
However, despite his movies’ success, it was reported earlier this year that his BBC One drama Taboo had resulted in a £2 million loss.
According to sources, Tom was left with a major shortfall after income was unable to cover the cost of producing the high-budget series.
An insider told The Sun at the time: "No matter who you are or how much money you're worth, £2 million is a lot of money to simply throw away."
Although the show is said to have made an income of £8.4 million, the source claimed that Tom would hope to cover the losses from the £10.4 million it cost to make through DVD and digital sales and syndication rights around the world.
The gritty show struggled with ratings on TV, with just 3.9 million tuning in for the third episode in January, but it managed to soar in online viewing figures, making it one of iPlayer's most popular programmes.
The Executive Producer of Taboo has since told Express.co.uk: "There has been no £2 million lost on the Taboo production.
"The cost of the production has been fully covered. These figures are taken from Interim accounts filed last year and are out of context and therefore misleading.
"Taboo Productions always had sufficient financing secured to complete and deliver the series."
