The plot is pretty simplistic. A plane crashes in the jungle and a baby is the only survivor. Cheetah brings the infant to Tarzan and Jane. Of course, Jane insists they will raise it as their own and acquiesces to the idea of calling the baby boy "Boy" (we can only wonder what would happen if the couple were to come across a second male child in terms of names). Boy (Johnny Shefield) is happy in his jungle home when suddenly a saffair made up of his parents' relatives arrives up the scene to begin a custody dispute, jungle style, which means involving a LOT of elephants.
The bottom line is that "Tarzan Finds a Son!" is the second best of the Weismuller Tarzan films, behind 1934's "Tarzan and His Mate," bringing out a paternal streak in the Lord of the Jungle that becomes him. The chemistry between the trio (okay, the quartet when you include Cheetah), makes this film work despite the limited vocabulary Weismuller's Tarzan has to work with in this series. Not to mention Boy has a pretty good variation of the Tarzan yell going for him. Of course, if you see this one be sure to check out "Tarzan's New York Adventure," where Boy is kidnapped by an evil circus promoter and taken to New York City where Tarzan and Jane follow to rescue him.
This installment certainly added extra dimension to both of their characters with Tarzan displaying paternal emotions for the character of Boy and Jane being revealed as not always making the right choice and having a disagreement with Tarzan that causes a rupture, however temporary, in their relationship.
By the time this installment was released in 1939 (it was the fourth in the Johnny Weissmuller Tarzan films) technology had developed considerly from the first film (Tarzan the Ape Man) in the early 30's which today seems abit primitive. In this film , apart from a few very fake vine swings , the special effects are wonderfully handled and show a real refinement.The underwater sequences are superbly handled and where actually filmed by the actors themselves. The film really has everthing from wild animals to rampaging tribes of natives, plane crashes etc. Everthing to make this film an exciting adventure story and one of the very best in the MGM Tarzan series
The stories main feature is of course the introduction of Johnny Sheffield as Boy, a character that remained in the rest of the Tarzan features. I wont relate the plot line of Boy's introduction into the story as other reviewers have already covered that but to say that Johhny Weissmuller personally picked young Sheffield for the role and their on screen chemistry is wonderful. I feel Boy's introduction adds a logical development to the Tarzan character and from now on the king of the jungle had a family in the true sense of the word.
No Tarzan film would be complete without its quota of villians and "Tarzan finds a Son" has a very exceptional list of fine character actors as supporting performers. The great Henry Stephenson appears fresh from his great performance in the previous years MGM classic "Marie Antoniette" as Boy's long lost great Uncle looking for the possible survivors of the earlier plane crash. Another great performer is Cecil B. DeMille regular Henry Wilcoxon who plays one of the white explorers. Both add a real prestige element to this film.
I think "Tarzan finds a Son" is a terrific piece of entertainment and one of the best in the MGM series. At this point the series was still alive and fresh and the expert direction by Richard Thorpe really keeps the action moving along. Enjoy!
This was another interesting, fast-moving Tarzan film with plenty of action and even a little more humor than normal.
The action scenes are hokey (shots of wild animals on a screen in back of the live actors) and even the background scenery is obviously painted but, hey, it's an old film. You just put up with, and vast amount of "darlings" uttered by "Jane" (Maureen O'Sullivan). However, the rest of the film is very entertaining, very good and even very clever at times.
The story is about Tarzan and Jane acquired "boy" (Johnny Sheffield) when the latter was five years old.
Overall: entertaining and one of the better Johnny Weissmuller-Tarzan entries.
