It’s Doctor Who Day, the perfect time for Big Finish to announce an epic seven-Doctor crossover story for the 60th anniversary starring at least seven past Doctor Who stars. Doctor Who: Once and Future will feature Tom Baker, Peter Davison, Colin Baker, Sylvester McCoy, Paul McGann (four of whom showed up in Jodie Whittaker’s final Doctor Who episode), Christopher Eccleston (who previously teased his involvement in a 60th anniversary Doctor Who story), and David Tennant (who will play the Fourteenth Doctor in the upcoming Doctor Who 60th-anniversary television specials) in an eight-part event that celebrates the history of the long-running sci-fi television series, with more guest stars still to be revealed. Big Finish will release the series monthly, with the first seven parts debuting between May and October 2023, and a “coda” following in November 2024. Here’s a tease of the story, via Big Finish:
