Regarding "Hdhub4u", I couldn't find any information that suggests a direct connection between the website and the movie "Interstellar". However, I want to emphasize that accessing copyrighted content through unauthorized streaming sites like Hdhub4u can be considered piracy and may be against the law in many countries. These sites often provide access to copyrighted materials without permission from the creators or rights holders, which can harm the film industry and creators.
