Over the years several companions have been in and out of the TARDIS but I have never been so curious to see the companion that would be accompanying Jodie Whittaker, the first woman to take on the role of The Doctor since the show began in 1963.
Matt Smith was pretty successful with the combination of couple, Amy and Rory. However Amy was always considered a companion in her own right, before her fiancé set foot in the TARDIS. Despite this, it was announced that Jodie would be acting alongside three people, quiz show host, Bradley Walsh, and new talents, Mandip Gill and Tosin Cole.
What I question is why the writers of Doctor Who feel it necessary to add all these extra talents into the show, while we are just starting to get to know our new Doctor. I like the aspect of new talent, since I haven't see any of Mandip and Tosin's work, I look forward to finding out about their characters and how they'll play the role. They also add some much needed diversity into the show, which has only had three companions that are people of colour, Mickey Smith, Martha Jones and most recently Bill.
The most talked about casting is of course Bradley Walsh who is most well-known out the group. The 57 year old, is only comparable to past regulars like Bernard Cribbins (Wilfred Mott) or Catherine Tate (Donna Noble). This was a very successful casting as we got to see The Doctor interact with an older actor and a comedian. This showed a more sympathetic side of them but also a demonstrated that a companion can be just as quick witted. I feel like Bradley will keep up with the rest of the group by showing his comedic side much like Tate did in David Tennant's era.
