The Wedding of Sarah Jane Smith was notable for the appearance of David Tennant as the Tenth Doctor and well known British actor Nigel Havers as Sarah's would-be suitor. It was the first time that the Doctor had appeared in any Doctor Who spin-offs — but the last time David Tennant played the Doctor during his original tenure. It was essentially filmed in the same production block as his final episode of Doctor Who, albeit in a different corner of the Upper Boat Studios.
The Trickster also returned for a third time. It would turn out to be his last appearance on the series, and his only direct confrontation with the Doctor, although he would be obliquely referenced in Turn Left and Torchwood: Miracle Day.
The show was due to feature Nicholas Courtney as the Brigadier, but his ill health prevented him from appearing. The Brig nevertheless does feature in the novelisation, offering a tantalising glimpse of what would have been the character's only televised meeting with a 21st century incarnation of the Doctor.
