“Ice House” (** out of four) was an ineffectual thriller about two friends (Greg Berman and Roger Wayne) who spend the night in an ice house on a frozen lake in Minnesota which leads to them unearthing dark secrets about one another that lead to hidden agendas and duplicity. Snowbound Minnesota locations and Steve Friederichson’s sleek cinematography are definite plusses but they easily outweigh the weak script and story which goes on far too long at nearly two hours. Might have worked better as a two-character play.
