These two pictures are screen shots from a 1958 film called Battle of the V1, which was filmed partly at Brighton Studios in St Nicholas Road and on location at Shoreham beach.
Was it in Portslade?
The film starred Michael Rennie and was directed by Vernon Sewell for Eros Films. The street could be almost anywhere in the area, although Portslade is likely. It is possible that the street no longer exists as there is a scene of a burning house that looks as though it could be one of the same properties.
What about the cinema?
However, the cinema ought to be more recognisable. One suggestion is the Pavilion in Portslade, although it doesn’t look like the only photo I can find of it. The advertising post on the left of the shot is part of the set dressing to make the Sussex location look like wartime Poland!
