Fun facts to check out! (if you like the BJ/Lyds thing):
When watching the movie, take a look at this:
When BJ and Lyds are getting married, and Adam drives into BJ's foot, the preacher is saying "And I now pronounce you man and --wife?" but he still says wife, even with the sound effects overlapping. (pay VERY close attention, might take a couple of tries, but it's there-lol.)
When BJ is stomping his foot from having it been driven into, Lydia is staring at her hand/ring finger in shock, in other words, the ring did get on her finger. (seriously, look)
After BJ is swallowed by the sandworm, and Lyds is looking around, notice how she seems to move her hands behind her a bit, as though hiding something, then brings them back in front, she even smiles like she has a secret.
Technicality: The tv show starts a 'year after they met' on their "Anniversary" of the day /they met/ which is ironically, when they got hitched, (if you go by the movie, which there are numerous instances that the writers meant for it to be) and the first episode is also when Lyds says 'you haven't changed since the day we met' and BJ replys 'hey, i like this suite' -in the movie he's wearing the pin-stripe suite, particular at the wedding scene/right before. Also BJ mentions how he's an 'illegal alien' and to get into her world hes gotta get married-to someone from her world-as in her, buuuut that should also work the other way around-now she can go into his world too. This is why she is able to in the TV show (once more, if you go by the movie). Also the reason she hasn't gotten preggy is because, as far as I can tell, she'd have to be a permanent resident in the Nietherworld/live in the Neitherworld in order to-notice in the episode when Lyds is almost married off to Bully the Crud, when BJ has a vision in the crystal ball of Lyds if he doesn't save her, her hair is like BJ's and she has several kids.
