Speaking at the Royal Television Society on Tuesday, Sept. 17, Beckham, 49, admitted that filming the project was “difficult” and resulted in him and his wife, Victoria Beckham, 50, feeling “nervous,” according to Variety .

"I can't lie, it worried me, it made me nervous, it made Victoria nervous," Beckham said about the Emmy-winning series 'Beckham' at The Royal Television Society's London Convention on Tuesday.

Speaking at the Royal Television Society conference in London, Beckham said it took him a long time to come around to the idea of a documentary, particularly because he “wasn’t ready” to discuss his career in the immediate wake of retirement.
