Intense heat

While the movie is set in Detriot, Michigan, most of the movie was shot in Dallas during the summertime.

However, this proved to be a major problem for one particular member of the cast.

For Peter, wearing his full RoboCop costume in the sweltering heat meant he was losing in excess of eight pounds of water weight a day, and so spent most of the time rehydrating or having cool air hoses stuffed into the costume.

He later said: ”There were 27 days of absolute - I wouldn't say ‘misery’ - but it really demanded a Zen sort of discipline.”
