Wrong Movie Poster - but impossible for me to fix or remove

The 36 minute film short "Alice (2009)" at https://www.imdb.com/title/tt1342823/
staring Tiffany Hofstetter, Arlene Newman-Van Asperen, has the wrong movie poster which instead features the 2009 TV MiniSeries here at https://www.imdb.com/title/tt1461312 staring Tim Curry, Kathy Bates, Matt Frewer. 

I am not able to find a true movie poster for the Short. 

I also tried but am completely unable to remove the wrong poster on the Short by myself.

Thanks in advance for fixing for us.
