MOMI (the Museum of the Moving Image) was a great museum run by the BFI, containing loads of information on the history of cinema as well as some fun 'hands-on' exhibits and live actors. Unfortunately, it closed four years ago and hasn't opened since.
Speaking to someone at the desk of the National Film Theatre, they said that it was originally hoped that MOMI would re-open in a new building. However, the funds didn't come through, and what with the
South Bank development coming to a halt, MOMI couldn't find a new home. The exhibits have been kept in storage, I was told, and it's hoped that they will be taken around to schools.
I found two stories from BBC News and Media Guardian which report that the BFI intend to use some of the material within a new Film Centre in the Jubilee Gardens, though I have no idea of whether this is still the intention.
MOMI was a fantastic attraction, and its demise is a great shame.
