I watched a really cheap English movie called "He Who Dares" which is (unsurprisingly) about the SAS. The logline calls it "Die Hard meets The Raid" and that much is true. However, it's Die Hard meets The Raid on a budget of 50p.
Some of the performances were good, some were awful and the script was patchy, I thought. Reading reviews, you'd think that everyone hated the film but I was surprised to see that there's a sequel (He Who Dares: Downing Street Mission).
The best thing about HWD 1 was the ever watchable Zara Pyhthian - I don't know why she's not a bigger star than she is to be honest.
