THE TRIALS OF O'BRIEN--the television series (and film)--episodes online at the moment:

 

The Trials of O'Brien was, as noted elsewhere in the blog, a 22-episode/single-season CBS television series that had the poor fortune of being slotted in 1965-66 against another new series, NBC's Get Smart, and a remarkably popular older series on ABC, The Lawrence Welk Show. CBS didn't seem inclined toward giving it another chance in a less viewer-deprived slot. Which is a pity, since it was a decent series, even if the humor in the production could be a bit broad at times, rather more deft in other instances. More or less, the regular cast included Peter Falk as gambling-addicted, reluctantly divorcing, somewhat eccentric defense attorney Daniel O'Brien (Falk apparently preferred this role to that of the not dissimilar Columbo);  his much put-upon but deft and devoted secretary Miss G (Elaine Stritch); his soon to be ex-wife and commercial artist Katie (Joanna Barnes); her mother, Margaret (Ilka Chase), his bookie, the Great McGonigle (David Burns), and a police officer of his acquaintance, Garrison (Dolph Sweet).

[And since this entry was first posted, most of the YouTube links have been removed...what I currently see have been relinked...though I wouldn't be surprised if this post is being used as a stalking horse.]

 

Circulating episodes of the series are mostly in not the best shape, after multi-generation dubbing from tape to tape...who knows if any legatee of Filmways or MGM have retained masters. Posted version of the one 2-part episode, filmed in color and released in foreign markets (and probably to US tv syndication) as a feature, looks rather better. (Click on the YouTube logo to watch them in full-screen.)

 

"Over Defence is Done": Pilot episode--guest stars include Murray Hamilton, Vincent Gardenia and Kathleen Cody. A rather hardboiled episode at times.

 

"Bargain Day on the Street of Regret": Ep. 1o2--guest stars include Herschel Bernardi, Rober Blake, Albert Dekker and Judi West.

 

"No Justice for the Judge": Ep. 103--guest stars include Burgess Meredith and Barnard Hughes.
