Dan Radcliffe will be seen on British televisions twice in the next week.

Firstly he will make an appearance in a pre-recorded segment for Comic Relief tonight. The Red Nose Day coverage will be on BBC1 tonight from 7pm and will last most of the night. It's unknown what exact time he'll be on, however some of the highlights of the evening are detailed here. Comic Relief, through the use of comedy, raises money for those in need in both Africa and the UK.

Following that, next Friday (March 23rd) he will be a guest on Friday Night with Jonathan Ross. This will be Dan's second time on the programme which airs on BBC1 at 10:40pm.
