Father and son Will and Jaden Smith were big winners at the annual Razzie awards, picking up three prizes for their sci-fi flop After Earth.
Jaden, 15, won the statuette for worst actor, while his famous father won the supporting actor Razzie.
The pair were also voted worst screen combo.
"It's an old Hollywood traditional that somebody who is a star tries to make members of their family a star, and sometimes it works and sometimes it doesn't," Razzies founder John Wilson told the BBC after the ceremony was over.
Taking place on the eve of the Oscars, the Razzies highlight the worst films of the past year.
The ceremony was held on Hollywood Boulevard just a short walk from the Oscars red carpet.
Movie 43's star ensemble cast could not save it from being a turkey
The worst picture prize went to Movie 43, a comedy anthology with an ensemble cast including Kate Winslet, Hugh Jackman and Halle Berry.
Described by one critic as "the Citizen Kane of awful", the film also won for worst screenplay (written by at least 19 people) and worst director (credited to 13 people).
Wilson said: "It's tasteless, it's stupid, it's insulting and it's sexist."
Tyler Perry (in drag) was named worst actress for A Madea Christmas, while Kim Kardashian was worst supporting actress for Tyler Perry's Temptation.
The Lone Ranger, starring Johnny Depp as Tonto, was worst remake or sequel.
Despite its eight nominations, Adam Sandler's hit film sequel Grown Ups 2 went home empty-handed.
Officially known as the Golden Raspberry Awards, the Razzies were created in 1980 "as the logical antidote to Tinsel Town's annual glut of self-congratulatory awards".
Winners generally fail to show up - although Halle Berry and Sandra Bullock have collected their gold spray-painted prizes in person.
As at the Oscars, the Razzies have an In Memoriam section, which this year included former Razzie nominee Peter O'Toole, the film critic Roger Ebert and Blockbuster video stores.
