Fresh from bringing his new comedy Come Fly with Me to our screens over Christmas, David Walliams (above) presents this compendium of guilty viewing pleasures: two hours' worth of clips from the television shows, films and adverts that are "so bad, they're good" (the programme-makers' promise, not ours). These include everything from Keanu Reeves being out-acted by a wooden stake in Bram Stoker's Dracula to the embarrassing roaring shark from Jaws 4: The Revenge and excruciating attempts by the BBC to get hip in the 1970s.
