As you can see in the picture I've taken from this answer (below) R2D2 can be pretty clearly seen in the opening battle in Star Trek (2009) and Star Trek Into Darkness (kudos Richard). My question: What is the out-of-universe reason for including R2D2 in a Star Trek film?

Bonus question: although I doubt there is one, is there an in-universe reason provided for R2 being here?

R2 in Star Trek

R2 Into Darkness

The answer is simple: Because JJ Abrams can.

From Yahoo movies:

"R2's really been in all of the movies I've done, really for no other reason than I'm a huge fan, and when I was a kid I realized that R2 was also in 'Close Encounters,'" Abrams told us at last night's "Star Trek Into Darkness" Blu-ray release party. "Actually, I'm putting a 'Star Wars' character into 'Star Trek' as an homage to 'Close Encounters.' So there you go."

People like R2D2 enough to put him everywhere:

There is no need for a convoluted answer to everything...

    Now we need the "Grand Unified R2 Fanfic" to tie all these appearances together in-canon.

I've expanded on this in my answer to the question Star Wars referencing Star Trek or vice-versa?, but the essence is that Lucas' company Industrial Light & Magic produced the visual effects for the Star Wars and Star Trek movies, as well as many others.

Chances are some of their employees were having fun.


Easy in-universe answer. Star Trek is set in a fictional future of our own planet. Star Wars already exists in our world. It would still exist in the future. Someone on one of the ships was a Star Wars fan, and built an R2 unit - which would probably not be hard in a Star Trek future.

    Is there a source for this claim?
