Siam Star

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.

FX/SFX: The green star and the thin red border forming.

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, we don't know what films 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.

Variant:

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.

FX/SFX: Scanimation.

Music/Sounds: The Star Wars Theme.

Music/Sounds Variantː 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.

Legacy: Not only did this stole music from Lucasfilm Ltd., it can remind you of Indra Film Production all because of the scanimate.
