this film really scared me as a child. the frighful noises the giant ants send out were very scary!great special effects for its day! the opening scene with the dazed little girl in shock from her encouter with Them,is quite haunting-begins in the new mexico desert..features james whitmore as the daunting policeman,james arness (of gunsmoke & the thing)- as the FBI Agent,and edmund gwenn,as the entomologist & his beautiful daughter Joan Weldon, trying to solve the mystery of the giant ants..great cast/plot and the whole story ends up in the storm drains of 1954 los angeles,probably the best of the atomic insect films-its my favorite...highly.recommed to all sci-fi-fiends..too right!!,til next time catch it and enjoy! dont know if its available on DVD,I have an old VHS copy .
