Transformers tops in Razzie's nomination

The fourth entry in the Transformers franchise leads this year's Razzie nominations, which single out the worst movies of the last 12 months.

Transformers: Age of Extinction, which made more than $1bn at the worldwide box office, has seven nominations including worst picture and screenplay.

Director Michael Bay has also been nominated for a Razzie, which launched in 1980 as a spoof of the Oscars.

Kirk Cameron's Saving Christmas and The Legend of Hercules received six nods.

They join action comedy Teenage Mutant Ninja Turtles - another Michael Bay production - and Nicolas Cage's thriller Left Behind in the worst picture category.
