Walking with... is a palaeontology media franchise produced and broadcast by the BBC Studios Science Unit. The franchise began with the series Walking with Dinosaurs (1999), created by Tim Haines. By far the most watched science programme in British television during the 20th century, Walking with Dinosaurs spawned companion material and four sequel series: Walking with Beasts (2001), Walking with Cavemen (2003), Sea Monsters (2003) and Walking with Monsters (2005). Each series uses a combination of computer-generated imagery and animatronics, incorporated with live action footage shot at various locations, to portray prehistoric animals in the style of a traditional nature documentary.
