Spider-Plant Man is a parody of Spider-Man, made for the Comic Relief 2005 appeal. It featured Rowan Atkinson as Peter Piper/Spider-Plant Man and Rachel Stevens as his love-interest Jane-Mary (parodying Mary-Jane Watson). Jim Broadbent also made an appearance, portraying Batman, and Tony Robinson as Robin.
PLOT:[i]Peter Piper, a photographer, visits a laboratory where a spider-plant with teeth has been created. Piper attempts to take a picture, but is bitten on the bottom by a plant coming down from the ceiling.
Piper leaves the lab via a back door, sits in a dark alley, sweating, and begins to turns green. His molecular structure is shown to be changing with the text "This means something nasty is happening". When he wakes up, he finds that when he stretches, plants shoot from his arms. He is also able to climb walls.
Piper is then shown sitting on a roof, when he sees that Jane-Mary is getting mugged. He goes to save her, but he realises that he needs a costume. He appears in the alley in an Indian costume, a fairy costume and eventually in his Spider-Plant suit. He saves Jane-Mary, who falls in love with him. He suggests to her that he might be Peter Piper, only to be told that Piper is a loser.
