The “Star Trek” franchise has been incorporating Easter eggs for years. In the original 1966 series, for instance, the Enterprise’s maintenance tunnels were famously dubbed “Jefferies tubes” in tribute to Matt Jefferies, the art director who crafted the design of the iconic ship. Easter eggs have remained a constant in “Trek” ever since, with new series such as “Strange New Worlds” featuring nods to past episodes and other franchises. In J.J. Abrams’ 2009 reboot film, an overlooked Easter egg includes a fleeting glimpse of Slusho, a beverage also featured in Abrams’ productions like “Fringe” and “Cloverfield.”

Slusho is a make-believe soft drink originating from Abrams’ TV show “Alias,” where it was initially named “Slush-O,” with its logo reminiscent of the “Icee” brand. The drink reappears in Abrams’ “Fringe,” and is also spotted in a convenience store scene in his 2011 film “Super 8.” However, most audiences recognize Slusho from the viral marketing of the 2008 monster flick “Cloverfield,” where it emerges as a product from a Japanese company using Seabed’s Nectar, a substance linked to the monstrous creature asleep beneath the sea.

In “Star Trek,” Cadet Uhura opts for Slusho at a bar on Earth. The question of whether Slusho is alcoholic or a future syntheholic version remains unanswered.

Slusho isn’t the only nod to other Abrams ventures in his “Star Trek” reboot. Both films he directed are replete with references to his prior work and even competing sci-fi franchises. For instance, R2-D2, the iconic droid from “Star Wars,” is spotted among space debris—years before Abrams directed two “Star Wars” films. Yet, the Easter eggs extend beyond this famous galaxy.

A notable Easter egg is the USS Kelvin, George Kirk’s (played by Chris Hemsworth) ship in the “Star Trek” movie’s opening scene. This is a personal tribute to Abrams’ father, which he includes in several of his projects. The entire timeline of these films is now called the Kelvin Timeline, as it was formed when the USS Kelvin faced a Romulan threat from the future. Tagruato, Slusho’s parent company, even makes a brief appearance in the cityscape, tying back to “Cloverfield.”

Though it may stretch the definition of an Easter egg, the involvement of longtime Abrams associate Greg Grunberg could qualify: He provides the voice for Kirk’s uncle in the 2009 film and portrays a Starfleet officer in “Star Trek Beyond,” thus becoming one of the rare actors featured in both “Trek” and “Star Wars.”
