The Cleaner Katsuki

Toby İstanbul'da (English: Toby in Istanbul) is a 1983 Turkish sports action-drama film directed by Zafer Par, an unofficial adaptation of The Ballad of Tobio by Osamu Tezuka and the 1975 film adaptation, relocating the setting to contemporary Turkey.

The film, part of a wave of low-budget Turksploitation action and superhero films produced during the 1950s to early 1980s that are infamously known for their unauthorized use of characters, among them were 3 Dev Adam, Turist Ömer Uzay Yolunda and most famously Dünyayı Kurtaran Adam.
