Holmes & Watson, starring Will Ferrell and John C Reilly, was the biggest "winner," taking four trophies including worst film and "worst rip-off."

Reilly also was named worst supporting actor in what Razzie founder John Wilson called the "clueless parody" of the classic British detective tale.

The tongue-in-cheek Razzies, created in 1980, serve as an antidote to Hollywood's Oscars.

Winners were announced a day before Sunday's Academy Awards ceremony - the highest honours in the movie industry.

Trump won two worst actor Razzies for appearing as himself in the 2018 documentaries Death of a Nation, from conservative film maker Dinesh D'Souza, and liberal Michael Moore's Fahrenheit 11/9.

White House aide Kellyanne Conway was voted worst supporting actress for her archival footage in Fahrenheit 11/9.

In an unusual twist, Melissa McCarthy was deemed worst actress, for her puppet comedy The Happytime Murders, as well as getting the Razzie Redeemer Award for her Oscar-nominated role in literary drama Can You Ever Forgive Me?

Gotti, about late New York Mafia boss John Gotti, escaped with no "wins" despite getting six nominations, including worst picture, actor and "worst screen combo" for stars John Travolta and his wife, Kelly Preston.

Nominees and winners of the Razzies are voted for online by around 1,000 Razzie members from 24 countries, who sign up online and pay a $US40 membership fee.
