Tim Rose, who will be back in the studio shooting Star Wars: Episode VIII next year, is only one of several coups at Harrogate Comic Con.
Also appearing at Rossett Sports Centre this Saturday will be a former Doctor Who and a star of Red Dwarf.
Organised by two local brothers, Paul and Gary Scarbrough, the event will see all three guest celebrities holding signing sessions for fans.
Rose, a puppeteer as well as an actor, first appeared as Admiral Ackbar, the military commander of the Rebel Alliance, back in 1983 in Star Wars Episode VI: Return of the Jedi, (1983), a role which he reprised in last year's world-wide box office smash Star Wars: The Force Awakens (2015).
Colin Baker has been a star of TV and screen for nearly 50 years and was the sixth incarnation of The Doctor in long-running TV series Doctor Who from 1984 to 1986.
Norman Lovett played Holly, one of the key characters, in the BBC hit TV comedy series Red Dwarf in series I, II, VII and VIII.
Some readers expressed surprise at Tom Rose’s scheduled appearance after news last month of the death of the actor playing the Star Wars character.
But that was the late Erik Bauersfeld who provided the voice of the character.
This exciting event runs from 10am to 4pm and also includes have cosplay costume competitions, a full size Tardis from Dr Who, prop replica vehicles from Fast and Furious movie and stalls selling all different types of memorabilia on TV and film.
Entry costs £3 for adults £3, £1.50 for under-16's while under 5's go free.
