Mentorn Films

1st Logo (November 16, 1988-1994)
Logo: On a black background, a "M" is on the center of the screen while a large chunk of it, masked in a circle, rotates counterclockwise and flashes multiple colors. Simultaneously, the cursive white text "films" draws in from the right side of the spinning circle cut-out and the gray letters "ENTORN", each inside a white box, flies in from the top and lands next to the top right of "M". After they are all together and the cut out stops spinning, "a" and "production", the former to the left of the logo and the latter to the bottom right of it all, fades in, followed by a copyright notice underneath.

Variants:
 * On series 4 of Challenge Anneka, "a" and "production" are in a slightly different font.
 * On I Drew Roger Rabbit, Thames' name appear within the copyright info, reading "© Mentorn Films / Thames T.V. 1988".
 * On series 4-5 of Challenge Anneka, this logo shares the screen with the 1988 BBC logo.
 * On The Bullion Boys, an alternate print version of the logo is used. Here, the circle mask is white and the boxes inside "MENTORN" are removed.

Technique: 2D animation.

Music/Sounds: The ending theme of the programme.

Availability: Seen on series 1-4 of Challenge Anneka and the documentaries Radical Radio: The Story of Kiss FM and I Drew Roger Rabbit.

2nd Logo (September 3, 1994-1997)
Logo: On a black background, several objects fly into the shot: four blue curved corners zoom out, a circular cut out of the letter "M" spinning counterclockwise from the left, and "MENTORN" from the right. Shortly before stopping, the same "films" text writes itself in the same fashion as before. After all of this, additional credit information appears underneath.

Variants:
 * A custom variant is used on Space Precinct where the logo is set on a space background and the gold text "GERRY ANDERSON" flies in from the bottom left alongside all the other objects. After they all stopped, aforementioned text shines.
 * On Today's the Day, a byline was added underneath, reading "A MENTORN MIDLANDS PRODUCTION".
 * On Today's the Day and series 5-7 of Challenge Anneka respectively, this logo shares the screen with the 1988 BBC logo.

Technique: CGI.
