The Francesca Beale Theater at Lincoln Center is hosting a run of “Keane,” director Lodge Kerrigan’s 2005 film about a missing child, upon the occasion of its transferral to a high-resolution 4K format from a 35mm camera negative. Those of us who missed the picture during its initial release will have to take it on faith that the “new” version is of a better or, at least different, visual quality.
