Can we draw the following hypothesis from the context?

Context:

The Wrath of the Gods is a 1914 American silent drama film directed by Reginald Barker, and starring Sessue Hayakawa, Tsuru Aoki, Frank Borzage, Thomas Kurihara and Henry Kotani in the lead roles. This was the first feature film appearance of Hayakawa and the directorial debut of Barker.

Hypothesis: Reginald Barker would not have had to worry about Thomas Korihara's performance in The Wrath of the Gods if Korihara had lost his voice.
