Other damage includes a gash on the bow section where block letters once spelled Titanic, part of the brass telemotor which once held the ship's wooden wheel is now twisted, and the crow's nest has completely deteriorated.[123] Canadian director James Cameron is responsible for some of the more significant damage during his expedition to the ship in 1995 to acquire footage for his film Titanic two years later. One of the MIR submersibles used on the expedition collided with the hull, damaging both and leaving fragments of the submersible's propeller shroud scattered around the superstructure. Captain Smith's quarters were heavily damaged by the collapse of the external bulkhead, which exposed the cabin's interior.[124]
