They're based in convenient locations including supermarkets, newsagents and train stations. Plus they're often open late and on Sundays. Keith doesn't explain the provenance of the quote he has reproduced, but it was the railway companies themselves who referred to the inward curve of the coach body below the waist as the "turn-under". Did you go to the Oscars for Farmageddon? Would you have liked to? Would you like to do more adult acting? bumble1 When filming a show like Gigglequiz, as well as thinking about my own physical characterisations, it’s also one of the most technically ambitious shows that I have been involved in. I play five characters on screen at the same time so I have to film each character individually and also remembering how they interact with each other in each take. We have a great technical team who are able to edit all the footage together to give the illusion that we are all performing at the same time in the same set.

I would love to have gone to the Oscars but due to the travel restrictions in place at the time, it wasn’t possible. However, I was thrilled to hear that the film had been nominated. It has to be the brontosaurus. Wouldn’t it be amazing to be able to see one of those again in the wild? They really are gentle giants! Snowmen are great fun to build. We built a Lord Tumble Snowman once. He had a top hat, scarf and a spotty cravat.As a child I used to watch Play School with Johnny Ball, Derek Griffiths and Floella Benjamin, and loved acting out the stories. At drama school, I was inspired by Phillip Schofield and Chris Jarvis in the CBBC Broom Cupboard and thought I’d like to perform in some family theatre and children’s television. I put a showreel together and managed to secure an audition for the theatre tour of Playdays, the show that took over from Play School. I landed the part of Mr Jolly. That was the very first part I played, which started my career in family entertainment. One of my favourite composers is Erich Korngold, who was an Austrian composer, and I particularly like his scores to Errol Flynn films such as The Adventures of Robin Hood and The Sea Hawk. John Williams is another favourite of mine; in some of his scores I think you can hear influences from the work of Korngold. I learned a lot about the history of film while working at the Museum of the Moving Image on the South Bank and attended many silent movie seasons there, as well as the Guardian interviews with various film directors across many genres of production. I think that is why I have a keen interest in all aspects of production, in television and on stage. I like to know how each department works, which I think is a good thing for an actor to have an understanding of. Items that are not available in store will take 3-5 working days (excluding weekends and bank holidays) to be delivered to your nominated store. Your comic timing with Robert the Robot [on CBeebies show Justin’s House] always reminds me of Laurel and Hardy – who inspires your characters? lime7 Since having a kid last year, I’ve been super impressed with the level of what I call “face work” in your performance. The degree of control you have over your face muscles to sell an idea/emotion/joke to kids is amazing. To what extent this is instinctual? Or are you thinking when you’re performing about what best to do with your face in each particular moment? Antzudan

Grandad Tumble is such a fun and endearing character to play. He tries to pass down his wisdom and knowledge to Mr Tumble, but it never seems to go to plan. The DJ scene was great fun and filming it is his shed was a clever idea. He is a very engaging and warm character that you can place in almost any situation. Do you find it impossible to go anywhere in public without having to “Tumble up” as it were for any kids who spot you or do grateful parents follow you around with heartfelt thanks for entertaining their little ones ? Thanks for all your thoughtful, funny output. mattpointblank Likewise, the railway companies themselves used the term "tumble-home" to refer to the inward cant of certain coaches above the waist line. Train will randomly reverse directions, make unpredictable movements and sounds to keep kids playing and laughing.When the programme Something Special was being developed about 20 years ago, I was asked to present the first four episodes. The programme uses Makaton, a signing system that was created over 40 years ago. I learned about 300 signs initially. Now, in preparation for each series, I learn a new set of words. It’s wonderful to be able to sign with so many families during the filming of each show. Makaton is an incredibly important communication tool that helps so many people. As well as filming in the studio we travel all over the UK and get to meet so many new friends. The Tumble Family seems to grow each year as well, with new characters providing an opportunity to develop new storylines for the Tumble segments in the show. I started performing again last summer, which was quite an emotional experience. One of my first performances was at Camp Bestival, at Lulworth Castle in Dorset. It was my 14th year there and the atmosphere was incredible. To be performing on the main stage after such a long time was awesome. I am currently performing in pantomime at the Hexagon theatre in Reading after a one-year absence and I’m thoroughly enjoying working on a theatre stage again. I love wildlife. I remember filming with giraffes once and thought they were the most graceful animals with beautiful markings and incredible eyes.
