Bernard Cribbins will be appearing at London Film & Comic Con on Sunday 8 July, at Kensington Olympia.
There’s also a Doctor Who talk scheduled for 10.30am, though it’s not yet clear which guests will be taking part.
Tickets to London Film & Comic Con cost £12 for early entry from 9am – it’s best to get there early if you want to meet popular guests as it’s first come first served. Standard entry from 11am is £6 for adults, or £3 for children aged 12 and under.
When you arrive you’ll need to collect a virtual queue ticket from Bernard Cribbins’s signing area, and buy a photoshoot ticket from the sales desk.
