He began his television career in the late 1990s, appearing in two episodes of Silent Witness.
In a particularly dramatic EastEnders storyline, Beckett's Jake Moon character shot and killed his brother Danny Moon (played by Jake Maskall).

He and Michael Madsen were both in the 2010 gangster movie The Big I Am.
