“Untitled Home Invasion Project” (** out of four) was a strained comedy about an actor (Jason Biggs) who- in desperation to save his faltering marriage to his wife (Meaghan Rath)- stages a home invasion from various fellow actors but naturally things don’t go as planned. Lively and buoyant comedy is crammed with offbeat humor but not enough to sustain a feature-length film and starts to wear out after a while. Pleasant enough directorial debut from Biggs and certainly is influenced by his “American Pie” series.
