No it wasn't, it was just shot at a different angle.
That's the thing. Yes, stuff was cut (Storm's tidal wave)
But most of what we got in the film were different versions of the same scenes in the trailers.
Wolverine's speech to Iceman before the final battle. Didn't get cut, it was changed.
Magneto's attacking the prison truck convoy... not cut, changed.
Certain shots of Cyclops at Alkali Lake, not cut, changed.
That's what most of the differences from the trailers are, just different shots / angles of the same scenes, or in some cases, different versions altogether that they felt would work better with the film.
