The choice to include a presenter was made to more easily allow audiences to see the scale of the creatures shown in the episodes.

For his role as the presenter of Land of Giants and Sea Monsters, Marven was nominated for a Royal Television Society Programme award.

While climbing, Marven accidentally put his finger under a vine before stepping on it, which led to one of his fingernails being pulled off.

The bandage and injury was incorporated into the story of the episode, with a Mononykus being depicted as biting Marven's finger.

[5] For his work in Land of Giants and in the subsequent miniseries Sea Monsters, also part of the Walking with... series and produced by Impossible Pictures, Nigel Marven was nominated for a Royal Television Society Programme award in 2004 for best presenter (factual).

[14] The series, titled Sea Monsters, was announced by the BBC on 29 July 2003[15] and first aired in November the same year.

[10] In addition to Sea Monsters, both Marven and James returned to prehistory with the series Prehistoric Park, also created by Impossible Pictures.

[16][17][18] Prehistoric Park is unconnected to the Walking with... series and was produced by ITV, ProSieben, Animal Planet and M6.
