“Summit Fever” (*1/2 out of four) was an overlong and underdone melodrama about four mountain-climbing friends (Ryan Phillippe, Freddie Thorp, Hannah New, and Mathilde Warnier) who attempt to scale one of the world’s most challenging mountains but this turns into a life-or-death expedition when a deadly storm traps them near the summit with no hopes of survival. Some of the mountain scenery is well-captured by cinematographer Adam Hall but film otherwise strangely cuts back-and-forth in time structure and can’t seem to make up its mind whether it’s a harrowing survival story or a character melodrama and thus falters at both. Phillippe is rock-solid as usual but this film is hardly the “summit” of his career.
