Firstly, it is directed by JJ Abrams (of Alias, Lost and Cloverfield fame), who I consider one of the better directing talents out there at the moment. I believe he is very good at mixing light-hearted moments throughout a very serious/action-packed storyline. This is one of the essentials to any Star Trek movie.
Secondly, it stars Zachary Quinto (Sylar in TV's Heroes) as Spock. He is one of the better actors to be found on Heroes and it will be good to see him take on such a large role where his performance will be judged against the much loved Leonard Nimoy (who will also makes a cameo appearance).
Thirdly, it stars Simon Pegg (see Shaun of the Dead, Hot Fuzz, Run Fat Boy Run, etc for details) as Scotty! I'll just keep it simple and say that anything with Simon Pegg with a Scottish accent in will be brilliant.
Lastly, I am a big Sci-Fi movie fan. As I have mentioned, I was not a fan of the Start Trek TV Shows. However, I have found the even numbered Star Trek Movies to be watchable, and even enjoyable! Other Sci-Fi Space action-based films such as Event Horizon, Pitch Black, Serenity and Total Recall, I consider to be some of my favourites. I hope, therefore, that I may be able to add this new Star Trek film to this list and allow it to break the rule that all odd-numbered Star Trek movies are rubbish!
At the time of writing this post, there is around 5 hours until the official trailer to the movie is released online for everyone to see on the official Star Trek Movie website. However, in the meantime, here's a lower quality bootleg version that somebody has recorded in a cinema and posted online.
