Hi. Some kind of screw-up regarding the two above-mentioned individuals with the same name (a middle name as added to on for disambiguation purposes). However, the credits are still comingled.

One of these (Elbert Smith) has two credits from the 1950s, the other (Elbert John Smith) has the 2012 credits. Additionally, the acting credit as "Henry Martin"
(https://www.imdb.com/title/tt0051418/?ref_=nm_flmg_act_8) which belonged to Elbert Smith was mistakenly ascribed to the other (Elbert John Smith).

Thanks.
