1. In Your Eyes (2014?)
Not a huge amount is known regarding In Your Eyes, other than Joss Whedon wrote it, and it hasn't been released yet. It has been described as a paranormal romance, and is the second feature to be produced by Whedon's own production company, Bellwether Pictures (Much Ado being the first). But the good thing about this film is that we don't need to know much about it. Just think of it this way, there's another Joss Whedon film on the way, and it's an original script as opposed to an adaptation. Although Whedon has stated that post production on the film has finished, it's more than fair to let the buzz about Much Ado die down before generating another one. Because of this I'd say to expect it to be released sometime next year, but long story short, even those who have seen Much Ado won't have to wait until Avengers 2 for more big screen Whedon!
Whedon Hallmark: As a personal low budget indie project, whatever this film is, it has the potential to beat even Serenity as the most undiluted Joss Whedon film.
