How to add an icon on the home screen to link to a video ?

I have an MP4 video on my Nexus 7 (16Gb) which my granddaughter likes to see but I have to load it through File Manager every time.
Is there a way to put an icon on the home screen so she can just tap it to start the video?
Thanks in advance....... :-)
