The Net 2.0 is a 2006 direct-to-video mystery thriller film written and produced by Rob Cowan and directed by Charles Winkler.
 It is nominally a sequel to the 1995 film "The Net" directed by his father Irwin Winkler, but has a separate and unrelated plot.

Dogme 95 was a filmmaking movement started in 1995 by the Danish directors Lars von Trier and Thomas Vinterberg, who created the "Dogme 95 Manifesto" and the "Vows of Chastity" (Danish: "kyskhedsløfter" ).
 These were rules to create filmmaking based on the traditional values of story, acting, and theme, and excluding the use of elaborate special effects or technology.
 It was an attempt to take back power for the director as artist, as opposed to the studio.
 They were later joined by fellow Danish directors Kristian Levring and Søren Kragh-Jacobsen, forming the Dogme 95 Collective or the Dogme Brethren.
 "Dogme" (] ) is the Danish word for dogma.

It's All About Love is a 2003 romance-drama film written and directed by Thomas Vinterberg.

 The production was led by Denmark's Nimbus Film, but the film was largely an international co-production, with involvement of companies from nine different countries in total.
