Only the River Knows

No comments yet

Only the River Knows is a brand new, 80-minute fly fishing film shot in New Zealand, Australia, Norway and Sweden.

The main part of the film takes place by the legendary Lethe River on New Zealand's wild and wondrous South Island. Back in 1988, one of the most iconic fly fishers of our time, Lars Lenth, spent three months exploring the fabled river and fishing for its abnormally large trout. At night, he would sit down in a remote cabin and write down his experiences in a journal.
Nearly 25 years later, the young trout bum Rolf Nylinder looses his way in the wilderness near Lethe. By chance, he finds the long-lost journal, full of insights about the very soul of fly fishing. Along with Rolf on the trip is documentarist Peter Christensen, filming their mostly failing attempts to catch trout, and Rolf's ever-growing obsession of the journal.

The entire journal of Lars Lenth has been reconstructed by an extensive and ambitious team of cinematographers and crew members. The young, sensitive and freedom-loving Lenth is played by Danish fly fishing ace and actor Mikkel Poppelhøj, who had to practise four hours daily for six months to be able to cast as well as the role necessitated.

Only the River Knows has been produced by Peter Christensen and Rolf Nylinder from Kokkaffe Conglomerate on a very tight budget (called Mastercard). Early reviews have been very positive, and we hope many of you out there will enjoy the film, and share the wonders of fly fishing with us. Here are a few:
"A Herculean effort", Ryan Peterson, Eastern Rises (we hope Ryan doesn't refer to the Disney character)
"Just when I thought fly fishing films couldn't get any better, Peter and Rolf raised the bar, yet again!", Nick Pujic, Fly Max Films

On our website onlytheriverknows.com you can find dealers or order the film directly through our webshop. Just click the link in the end of the film. Every dollars, dime and cent will go into making new film, and we feel blessed to have received so much support from the fly fishing world already.

Enjoy and lots of love,
Peter and Rolf

Long story short

Long story longer

The Global FlyFisher has been online since the mid-90's and has been free to access for everybody since day one – and will stay free for as long as I run it.
But that doesn't mean that it's free to run.
It costs money to drive a large site like this.
See more details about what you can do to help in this blog post.

The Global FlyFisher was updated to a new publishing system early March 2025, and there may still be a few glitches while the last bits get fixed. If you meet anything that doesn't work, please let me know.
