This film about a couple of straight guys having to rehearse and then perform a gay sex scene together is a real gem. First of all, an aperçu about the leads. They are both straight hunks, the sort of man most gay guys would hope might be gay or, as a minimum, bi.
As they rehearse their rôles together the director and scriptwriter cleverly and slowly engender a feeling of "are they actually really gay". In the end we see the film they are meant to be appearing in and all doubts are gone. These guys give a convincing performance of a pair of gay lovers forty years ago.
Except there's an epilogue. The guys appear in real life explaining their sexuality and life circumstances. They're straight. But, blooming hell they were so convincing as queers.
As a glimpse into make believe this film would be hard to beat. Despite the coda, I'm still left wondering.
