A Fly Fishing Short Film.

Kristallklar tells the tale of a hidden river holding wild brown trout near the border of Luxembourg and Germany. Find out about this magical river from the perspective of Kirill, who recently acquired the lease to the fishing rights of the river and a small tributary thereof. 


It captures the essence of a fly fishing adventure on the river embarked on by Kirill and two companions: Nic, a fly fishing scientist and myself, Simon the film maker.


The journey is a beautiful one and tries to capture the feeling of the magnificent surroundings and being at peace on the river. It also delves into topics of conservation of nature and the plans to re-stock the river with native crayfish which vanished from the river.


A lot of love went into this film and I hope it inspires those around the world to find a love for the outdoors and to preserve it for many years to come.

Runtime: 14m52s

Official selection, Rise Fly Fishing Film Festival 2022


This beautiful private stream is located in Western Germany. Tucked away from the world. The water is home to wild born trout and the land home to animals of the forest.

This unreal fishing experience in the area pictured in the film is kept a secret but may be fished by contacting Kirill.

Filmed and edited by Simon Kay (Si), the founder of

On The Fly Kreativ and a passionate fly fisher and filmmaker.

The project was filmed over the course of 5 days with mirrorless cameras and waders with many close calls with slips on the water! The occasional drone and underwater shot just added the subtle extra layers to further immerse the audience into the experience.

The film was made with the idea of bringing the audience along on the adventure in a dream-like world and the colour grade emphasizes this with a warm nostalgic feel. 

The most important thing was that it was a memorable and extremely enjoyable experience for everyone involved.

Definitely not the last On The Fly Kreativ Production on this piece of water.


A huge thank you to Kirill and Nic. Without the two of them this film would not have existed.

Kirill is an extremely knowledgeable local fly fisher and guide. Time spent on the water with him is filled with interesting facts about the water, the  area and where to find fish based on his intimate knowledge of the river. As the leaseholder of the rights to fish the river as well as someone with an immense love of nature, he spends almost every day on the water either fishing, researching, improving the environment. Also, watching him cast his 6ft 3wt rod into seemingly impossible areas is a spectacle to be marvelled at.

Nic resides in Luxembourg conducting research and completing his PhD in a topic far too complex for a verbal description in this paragraph (but relating to water movements underground, I think).  He has also been flinging a fly rod since his teen years and it shows. If Nic blanks on a section of water it is not due to bad luck but because there are no fish there. Nic is a good friend of Kirill's as well as a guide to a select few both on this river as well as the rivers of Luxembourg.

5 days with them on the river fishing, learning and laughing made this film possible.


Kirill has decided to open the river to a select few clients for guided trips (with himself or Nic).

If you have the same mindset when it comes to the preservation of wild beautiful places this is an amazing opportunity.
