1st logo (1978-1980s)
Logo: On a blue background, we see the Siam Star logo (which is 5 boomerangs connecting to a star) in lime green form itself, which is that the 5 boomerangs pop up one by one. Then, a red rectangle shows up, as well as the company name & text (Presents) in white.
Technique: Cel animation.
Music/Sounds: An orchestral fanfare which sounds distorted (due to film deterioration) ending with a timpani hit.
Availability: Seen on Thai movies at the time. Considering this company's obscurity, it's unknown what films did they make.
2nd logo (1980-1990)
Logo: We see a starry space background. Then we see the Siam Star logo in red forming itself with scanimate for nearly 5 seconds. When the logo is done, everything behind it "shines" 5 times.
- There's a variant that existed where instead of a space background, we see a gray room where the Siam Star logo & the company name in English & Thai all in white are shown. After 7 seconds of this, a Jeep goes by the logo & text. It stops, & it reveals who is driving the Jeep by him getting out of it. We zoom into the man to reveal him wearing a tuxedo & a hat. He bends down & he speaks while red text in Thai show up in cursive. The rest is him speaking while the camera zooms into his face.
- There's another variant where the logo cuts off the Scanimation.
Music/Sounds: A drum beat, followed by a majestic synth fanfare.
Music/Sounds Variant: In Ms. Yen Ruedee, it have the opening theme. In the Variant above, it's 2 people speaking.
Availability: The normal variant is not known yet. The variants can be seen in Ms. Yen Ruedee & Madam Yihub.
