Over the years, there have been some important videos produced about the Divine Mercy Message and Devotion. One recent video (March, 2007) that is quite well done is 
the latest version of Tell All Souls About My Mercy. Older versions have been simply a recording of the live presentation of Dave and Joan Maroney, but this is actually a video, with numerous sources, that is based on the presentation. It introduces the viewer to the life of St. Faustina and elements of the Divine Mercy devotion, along with some important passages from her Diary.
I strongly recommend this newest version of Tell All Souls About My Mercy, especially to people who don’t know much about the message and would like to learn more. The Time for Mercy video is badly outdated, and this helps as an “update.”
