Filming began in London in March 2014, with David Gyasii cast in the lead role, but he left the production after injuring his leg. With O-T Fagbenle recast in the lead role, filming re-commenced in April 2014.
Part of the filming took place in Gravesend, at Nell's Cafe, which doubled for a cafe called 'Planet Thanet', with the UNIT base scenes filmed on location in Keybridge House, a decommissioned British Telecom building in Vauxhall.
The series received a universally negative response from critics. It was given 1/5 stars by Michael Hogan who, writing in The Telegraph, said "O-T Fagbenle tried his best to inject some life into the limp script - huffing, puffing, pouting and glowering - but he's too good for this hokum".
