Interesting tidbit on the Insider podcast. They actually blew up that building in real life. It was a fast food restaurant that was going to be torn down, so they dressed the inside of it to look like a real restaurant, then destroyed everything, then blew it up. No visual effects. All practical effects. And even more interesting, they said that rigging the shot to show the frozen chicken sliding into the fryer was much more complex and required CGI (to remove fishing line that was used to pull the chicken down the slope).
I still wonder whether the real reason Jimmy and Kim got married is to take advantage of the marital privilege. That seems like a really stupid reason, and maybe just something Jimmy said to Huell to end the conversation. First, Kim proposed the marriage and she didn't know at the time that Jimmy was about to get very deeply involved with the Cartel. Second, if Kim really thinks Jimmy is going to be doing hardcore illegal stuff that would lead to her being questioned, I don't think she'd want to still be with Jimmy. And finally, Kim seems like she's honorable enough, and respects the law enough, that even if she were not required to testify against Jimmy, she still would do it if she knew he was guilty. Unfortunately, they didn't discuss this motive on the Insider podcast.
