I also consider this a sleeper. Found it humorous, well played and well written. Heston as serious soldier on off beat mission. Ilsa Martinelli (far from plains of Africa) as love interest, but not so lovely as big chested actress who plays her sister. Harry Guardino in yet another GI role. Barry Fitzgerald even more typecast as Irish priest. Good character actors for kid and bumptious dad. Great bit by Randolph Anders as Werhmacht Oberst. Worth looking for. Couldn't help comparing this "war" movie with Band of Brothers.
