No
No, Julia Roberts had nothing to do with Star Trek: First Contact.
The posted gross for Star Trek: First Contact was $150 Million.
If you are talking about the Star Trek enterprise E from movies such as Nemesis, Insurrection and First Contact, it is, and I quote from the movie Star Trek First Contact Picard: "There are 24 decks, almost 700 metres long"
I do not think there is an official "Star Trek day", but First Contact Day (April 25th) could be considered as "Star Trek day".
Right now!! One of the best Star Trek movies made.

Avery Brooks did not voice a character in "Star Trek: First Contact." He is best known for his role as Captain Benjamin Sisko in "Star Trek: Deep Space Nine." "First Contact," released in 1996, primarily features characters from "Star Trek: The Next Generation," including Captain Jean-Luc Picard, portrayed by Patrick Stewart. Brooks' portrayal of Sisko became iconic, but he did not participate in this particular film.
