10 Most Infuriating Movie Cliffhangers

2. 28 Months Later? - 28 Weeks Later

Here's another film that promises a follow-up in its cliffhanger yet to date just hasn't delivered upon it. Once the protagonists escape the rage-infected invasion in the UK, they escape to France, where we find out that things aren't a whole lot better. The final shot is of a French accent asking for help through a helicopter radio, as we see a group of rage-infected folk running through a train station out into the open, revealing the Eiffel Tower in the distance.

This was obviously to set up 28 Months Later, the finale in the trilogy that Danny Boyle still claims is going to happen. However, given that it's been almost 10 years since it came out, I think it's safe to say that the prospect of it actually getting made is unlikely, meaning this is nothing more than a frustrating tease.
