Amy Adams shot this musical in 2006 - right after "Junebug" and just before "Enchanted".
I contacted Identity Films about "Moonlight Serenade" a few weeks ago. One of the producers told me that the film was never released. It was stuck in post-production somehow. No word on when it will be out :-(
It's a musical/romantic comedy directed by Giancarlo Tallarico starring Scottish actor Alec Newman. Amy is pictured on the left with jazz organist Joey De Francesco on the Los Angeles set.
Hopefully we'll get to see it eventually so, until then, keep your fingers crossed!
