1st Logo (January 24, 1975-May 5, 1978, December 3, 1982-July 4, 1997)
Logo: On a space background, we see a blue hand pointing at a spinning yellow ring fading in, which also causes a red triangle to wipe and fade in. The camera then rotates 86 degrees, revealing the end of a silver trident. Yet again, the camera rotates which reveals, what appears to be, a pink foot with a red star on top. Lastly the camera zooms out, revealing a symbol with all of the said objects from the triangle, which causes the words "TRIMURTI" and "FILMS" in yellow to appear between the trident along with the Hindi translation in red appearing below the symbol.

Variant: An in-credit variant exists in Mohra where the symbol in white and the English translation in red underneath it appear superimposed over the opening scene of the movie.
