Calling Scotland Yard (1953) - 13 short films made for US tv, never shown on British screens. Some were made into cinema compilations.
The Vise (1954/5) - made for US again, but some of this series later showed up in Britain renamed 'Tension' (65 twenty five minute films= picture #13)
Mark Saber (1955-59) - later as Saber of London, the Danzigers' biggest success (65 Mark Saber, 91 Saber of London, total 156)
Man from Interpol (1959/60) - though this series of 39 stories amazingly received network status in America, that soon changed
The Cheaters (1960/1) - to my mind the Danzigers' most accomplished series (39 stories)
Richard the Lionheart (1961) - a last tv series of 39 stories, different to any of the preceding, one that deserved a better fate
