25 Mbps is really a very high bitrate for 1080p24 H.264! using single-slice x264 with good settings. I'd expect Level 4.0 x264 with 25 Mbps peaks to be transparent for almost all real-world film content. 1080i30 without MBAFF, could be an issue, but 24p should be just fine. HD DVD titles looked great with older encoders, shorter GOPs, and similar or even lower peaks (one highly rated title was VC-1 with 13 Mbps ABR and 19 Mbps PBR).

Remember Blu-ray's peak bitrate was defined for MPEG-2 applications. It's rather overkill for modern codecs.
