After the original format of Top Gear was cancelled by the BBC, Wilman and ex-presenter Clarkson pitched a new format. Apart from Top Gear, Wilman has worked with Clarkson on a number of other television projects.
Wilman and Clarkson's company Bedder 6, which handled merchandise and international distribution for Top Gear, earned over £149m in revenue in 2012, prior to a restructuring that gave BBC Worldwide full control of the Top Gear rights.
In April 2015, Wilman announced that he had resigned as executive producer of BBC Television's Top Gear following Jeremy Clarkson's exit in March 2015, owing to Clarkson's attack on a producer. As of 2016, Wilman is the executive producer of The Grand Tour that Clarkson, Richard Hammond, and James May are producing via their company W. Chump & Sons for release via Amazon Video to Amazon Prime customers.
