Lifeboat was released by Shock, and Lost Horizon by Via Vision - both independent Aussie labels. To my (consumer) knowledge, they are unconnected to Madman. I checked my Blu-rays by Madman, and the four most recent releases (2017 to 2019) played on my region A player. Two earlier releases did not and were only playable on my region B player. I don’t think too much can be read into that in terms of predicting whether the upcoming releases will be region free, as that will no doubt be driven by the distribution agreements they’ve struck. What it seems to indicate though is that where possible, they try to release unlocked product for as wide a distribution as possible.
