The pair faced off countless times as deadly rivals Krystle Carrington and Alexis Colby on the show, but they were later said to have fallen out after working in a stage play together, and are no longer in contact.
Following on from the successful revival of fellow '80s soap opera Dallas last year (12), rumours are rife that the stars of Dynasty are pushing for a similar relaunch - and Evans is adamant she would love to work with Collins again.
She tells Britain's Daily Mail, "There has been chatter (about a Dynasty relaunch) but that doesn't mean it's going to be done... (But) I'd have no problem working with her. In fact, I'm extremely grateful to Joan for helping make Dynasty the show it was."
The film is almost half an hour longer than 'The Force Awakens'.
The actress will no doubt be returning for the long-running FX series.
The film is expected to continue without Mendes' involvement.
