Dualstar Entertainment

Background
Dualstar Entertainment was a production company owned and founded by Mary-Kate and Ashley Olsen. It produced a string of films and TV series featuring the twins throughout the 1990s and the early 2000s, but after the box office and critical failure of New York Minute, the company struggled to keep up operations. After being put into dormancy in 2007, the company was later revived in 2013 for a series of fragrances.

1st Logo (October 30, 1993)
Logo: Just the words "Times New Roman" and "Times New Roman" sliding from the left and right respectively on a black background.

FX/SFX: Th text sliding.

Music/Sounds: The ending theme of the movie.

Availability: Only seen on Double, Double, Toil and Trouble.

2nd Logo (November 19, 1994-May 7, 2004)
Logo: Against a nighttime sky background, we see a shiny round blue object turn to the left. Two crescent shapes appear from the right as several light streaks fly across it from the lower left, forming a "D" with a crescent. It flashes and moves slightly upward, and the words "DUALSTAR ENTERTAINMENT GROUP" or "DUALSTAR PRODUCTIONS", all arranged vertically, appear below.

Variants:
 * On TV shows, the logo either begins with a sped-up version of the long version, or starts with the crescent forming.

FX/SFX: The "D" turning, the light streaks, and final formation of the "D". Well-animated CGI for the time, which holds up pretty well today

Music/Sounds: A dramatic string tune ending in a 2-note fanfare.

Music/Sound Variants:
 * Three variants of the main jingle exist. One is the full version (seen mostly on movies from the company), another is a slightly shorter version (seen at the end of some Mary-Kate and Ashley TV shows), and a warp-speed version that plays the first 6 string notes before cutting to the last note of the theme (seen on some episodes of So Little Time).
 * On most TV shows with this logo, the end theme was used.

Availability: Appears on many films and TV series from Mary-Kate and Ashley, such as Switching Goals and So Little Time.

Editor's Note: It's a bit dark and dramatic, but there's nothing too scary about it.
