 * There is a variant where "ENTERTAINMENT" isn’t in italics, which also uses white text.
 * On Spider!, the text appears with the 1988 BBC Enterprises logo.

(September 27, 1999-2008)
Logo: On a black background, a stylized fox looking up at three stars and a light blue butterfly morphs into view. The latter two objects fly around as the fox, while remaining in its position, tries catching them. After the butterfly and stars wrap around and form a bottom curved arc, the fox leaps towards them and freezes, leaving two whooshes behind. Then, a quadrilateral fades in behind the objects, followed by "Silver Fox FILMS" in a written font and with shading.

Variants:
 * An in-credit variant exists. Additionally, the text is 2D.
 * Sometimes, the logo shares the screen with other logos including the 1997 BBC logo.
 * On Angelmouse, a print version of the above variant is seen.
 * On Harry and His Bucket Full of Dinosaurs, the text resembles the one described in the animated logo. "In Association With" is displayed on top of the logo.

FX/SFX: 2D animation.

Music/Sounds: None.

Availability: Rare.
 * Can be seen on Angelmouse, Bounty Hamster, Harry and His Bucket Full of Dinosaurs, among other cartoons they have produced.
 * The in-credit variant is more common than the standard logo, the latter of which can only be found on their animation clips and showreel on YouTube.
 * This logo is intact on the My Friend Angelmouse VHS release.
