Bundle Baaz was the last film Shammi Kapoor had directed as he faced difficulties to make a film. He said "Direction was not my cup of tea." He was to direct his third film for producer B.S.Khanna, but the film was shelved instead B.S.Khanna produced Kudrat, which was written and directed by Chetan Anand.
Although Shammi Kapoor and Rajesh Khanna were in Andaz a few years earlier but with the latter in a special appearance, this film was the first time the two appeared with each other.
Shammi kapoor made his debut as director in this film.
Rajesh Khanna had threatened to throw out Ranjeet of films after they had a confrontation on the sets of Bundelbaaz. The provocation was that Ranjeet had walked out of the sets after waiting for Rajesh for six hours.
Rajesh Khanna wanted to delay the release of the film because he wanted Mehbooba to release first. This angered Shammi to no end.
