Since a few people have asked and since there's room for confusion:
The KAS Creations film of "I Remember the Future" is in fact eligible to be nominated for the Hugo Award this year in the Best Dramatic Presentation, Short Form category. That is because the film festival showings that began in 2014 started the clock, and so it can be nominated in the Hugos for 2015.
Oddly, though, Science Fiction and Fantasy Writers of America has different rules for the Bradbury Award. They have ruled that it is not eligible for nomination until it gets a wider release. So if you're a member of SFWA, don't bother considering it for the Bradbury, but don't let that ruling affect how you fill out your Hugo ballot.
If you are a member of last year's, this year's, or next year's Worldcon, you are eligible to fill out a nominating ballot for the Hugos. As it so happens, tomorrow is the deadline to join this year's Worldcon in time to nominate for the Hugos, although the nominating deadline is in March. If you want to join Worldcon, visit https://sasquan.swoc.us/sasquan/reg.php
. You can join online; current cost for a Supporting Membership is US$40. (It is likely that besides all Worldcon publications, this year's members will receive a packet of Hugo-nominated ebooks and other works once the ballot is set, well worth the cost of the membership.)
