GK Productions

Background
This is the vanity plate of David Greenwalt. Jim Kouf joined the company in 2011.

(October 12, 1999-May 23, 2000)
Logo: On top of the Kuzui Enterprises and Sandollar Television logos on a purple background, we see a square with two sections. The section has text reading the company name. On the bottom is a illustration of a wolf seen howling over the moon.

Variants: On the episode "Lonely Heart", the logo is replaced with simple text reading the company's name and the aforementioned logos below, on the same metal background as usual.

Technique: None.

Music/Sounds: None.

Availability: Seen on the first season of Angel (excluding the first two episodes).

(September 26, 2000-February 6, 2004)
Logo: We see the back of a /white camper with a California license plate which reads "LAZYDAVE" on the first half. The camper then moves forward and merges to the left, revealing a street. The text "DAVID GREENWALT productions" is seen on the upper left.

Variant: On Angel, the logo is placed at the top (and squished as a result) above the aforementioned logos like before.

Technique: Live-action footage, which is fast-forward.

Music/Sounds: A kid saying "Dad, let's go!". On Angel, a half-hearted Elvis Presley impersonator says "Thank you, thank you very much" followed by the sound of tires revving.

Availability: Seen on Jake 2.0, Miracles and seasons 2 and 3 of Angel.

(October 28, 2011-March 31, 2017)
Logo: On a white gradient background, we see a canvas with a crude portrait of David Greenwalt and Jim Kouf. Soon, the canvas falls off the screen, revealing dust that forms the words Courier Times New Roman

Technique: Computer animation.

Music/Sounds: None.

Availability: Seen on Grimm.
