Meanwhile, 'Riverdale' closed down production in March due to the coronavirus pandemic.

The drama series - which was being filmed in Vancouver, Canada - halted work on its fourth season after an unnamed "team member" came into contact with someone suffering from the virus.

A statement from Warner Bros. Television said at the time: "We have been made aware that a team member from 'Riverdale', which is produced in Vancouver, was recently in contact with a person who has tested positive for COVID-19.

"The team member is currently receiving medical evaluation.

"We are working closely with the appropriate authorities and health agencies in Vancouver to identify and contact all individuals who may have come into direct contact with our team member. The health and safety of our employees, casts and crews is always our top priority."
