Baburao Patel's review in the September 1938 issue was favourable to the director "Directed by a man who enjoys a good reputation as a journalist… Mr. Chaturbhuj Doshi has given an excellent account of himself as a director considering that this is his very first effort", claiming it to be the "best picture coming out during the year from the Ranjit Studio".

Musafir in 1940 was a comedy costume drama, which had Charlie playing a prince who on his return finds his kingdom in disarray.
