Legendary - La tomba del dragone

Scott Adkins was rehabilitating his knee from an injury and taking a break from making action films, hence the lack of big stunts and fights on his part (which was not what the project was about anyway).

Harker's opening narration ran: "Biologists will tell you that every living creature on the planet has been discovered, that there's no room for surprises--if you don't count bugs, that is."

In fact, many new non-insect species are discovered every year. In just the year 2016, over 18,000 total new species were discovered. In the first decade of the 21st century, over 300 mammals alone were discovered, including monkeys in Tanzania and Burma and a leopard in Indonesia. Biologists fight to end deforestation and global warming because they know how much potential there is for further great new discoveries like these.

Some of the opening credits are shown over swirly, funkadelic, psychedelic animated blobs...
