During his years as an art director/set designer, Daniel Haller learned how to achieve the "mostest with the leastest" under the tutelage of quickie-movie king Roger Corman. Haller's ability to achieve depth of field in his inexpensive sets (usually by rearranging furniture, doors and arches from shot to shot) won him the admiration of everyone in the low-budget field. In 1967, Haller made his directorial bow with Die, Monster, Die. His best theatrical feature was 1970's The Dunwich Horror, a disturbingly effective adaptation of the H. P. Lovecraft classic. Daniel Haller has since been most active in television, directing such made-for-TV features as Little Women (1978) and Buck Rogers in the 25th Century (1979).
